Top 10 Best American Idol Contestants of All Time

American Idol has given us some of the most memorable voices in modern music. From powerhouse vocalists to genre-bending artists, the show has launched careers that continue to shape the industry.

Some contestants went on to win it all, while others found massive success despite falling short of the title. Either way, the talent that has come through the competition is undeniable.

This list highlights the best contestants to ever take the Idol stage.

The Top Ten

Adam Lambert

Adam Mitchel Lambert (born January 29, 1982) is an American singer, songwriter, and stage actor. He rose to prominence as the runner-up on the eighth season of American Idol in 2009. Since then, he has sold over 2.5 million albums and five million singles worldwide.

If Elvis Presley and Freddie Mercury had a love child, Adam Lambert would be the result. Adam Lambert possesses all the skills and qualities that make a great artist: a beautiful voice with a seemingly limitless range, great stage presence, and a natural ability to engage the audience with his performance. The band Queen even invited Adam to join as their new frontman. It doesn't matter that he didn't win Idol. If Queen invites you to join their band, you are an AMAZING singer. Adam was the true winner of the 8th season of American Idol, and America made a HUGE mistake by not voting him as the winner.

The thing about Adam is, he stays with you in your mind and heart. He comes across as such a beautiful person. There are many singers who have range and a beautiful sound, but Adam is just mesmerizing and has that "it" factor, that intangible thing that makes you so high you can't come down. I have seen him with Queen and on his solo tour, and both times it's been a high like a first love. Watching the Queen documentary brought that same feeling again. I have liked a lot of American Idol contestants, but Adam is a special kind of magic.
Watching him mentor this season and seeing contestants not even try to do Queen just shows the elite level he is at. I can't even watch American Idol after that. The best crop of Idol hopefuls ever? Really...
Kelly Clarkson

Kelly Brianne Clarkson is an American singer, songwriter, and children's book author. She rose to fame in 2002 after winning the inaugural season of American Idol, which earned her a record deal with RCA Records. Clarkson's debut single, "A Moment Like This," topped the US Billboard Hot 100 and became... read more

The first and the best (by a mile according to Simon) Idol contestant or winner. The most clearly best vocalist to ever step foot on the Idol stage. Actually, she is one of the great voices in music today. She can hold her own against anyone when it comes to singing. She was the first Idol, and American Idol never found anybody better. They searched but never found the next Kelly Clarkson.

Kelly Clarkson is by far one of the best female singers ever, not to mention that she was the first person to win the first season of American Idol. She has an amazing voice and so many incredible songs. Just listen to her song Stronger! I especially love her song Underneath the Tree. That's my number one favorite Christmas song of all time. She also has such a soulful voice. She is one of the reasons the music industry is such a huge success all the time. Let's never forget that. Because Kelly Clarkson is something! -Fender4Life
Clay Aiken

American Idol had its best viewership ever when Clay was on. The AI2 finale totals were never beaten. Also, the next best ratings were during AI5 when Clay made an appearance, which is by far the most memorable. Michael Sandecki won an award for the best impersonation of Clay Aiken, and Clay made an appearance. It was epic.
The best performance ever on Idol was Clay's "Bridge Over Troubled Waters." He's had a fantastic singing career, as well as his own foundation for kids, served as a UNICEF Ambassador, and even ran for Congress. It seems to me this is what an American Idol is all about.

Clay has that star quality very few artists from Idol have shown. I have never heard anything like his voice, the range, his falsetto, and his phrasing in which he articulates every word. In fact, he can hold a note longer than I can hold my breath. And nobody can sing Christmas songs like Clay. He absolutely should have won Idol, and everyone knows it. I miss him and hopefully, he will do Broadway or concerts again soon. I had never thought any singer could steal my heart. However, Clay has, and I want the excitement to continue.
Chris Daughtry

Christopher Adam "Chris" Daughtry is an American musician and actor, best known as the lead vocalist and rhythm guitarist for the rock band Daughtry. He gained national fame as the fourth-place finalist on the fifth season of American Idol. Since then, he has released multiple albums and toured extensively.... read more

Why is Chris down here?! He has had hit after hit on every album. Baptized is probably his best so far. His vocal range is amazing, and his music is beyond perfect. Please, just move Chris to the top 5 at least.

Bo Bice introduced rock to Idol, but Daughtry revolutionized it. He totally killed the season, and his performance of Hemorrhage was incredible.

Adam Lambert and Chris Daughtry are two of my favorite singers, but Chris is a little bit better. He's great!
David Cook

David Roland Cook is an American rock singer-songwriter who rose to fame after winning the seventh season of American Idol in 2008. His self-titled major-label debut album was released later that year. He has since released several albums and continues to perform.

Should be number one. A complete genius who changed the show forever. Artist > Singer.
Haley Reinhart

Haley Elizabeth Reinhart is an American singer, songwriter, and voice actress from Wheeling, Illinois, a suburb of Chicago. She rose to fame after finishing third on the tenth season of American Idol in 2011. Reinhart has since released several albums and is also known for her work with the musical group... read more

Adam Lambert on Haley: "I love the sound of her voice, the texture of it. Musically, her choices are incredible. I don't even think people are realizing the things that she's doing vocally. I think it's because she's so effortless about it."
Melinda Doolittle: "This girl can just flat out sing. I was watching the show last night with some of my favorite singers and we were in awe of what her voice can do. She can go from a raspy tone to one that is as clear as a bell in a matter of seconds. She has the vocal flexibility of a singer twice her age. She is amazing."
Jackie Tohn: "Haley for me is one of the freshest girls I've seen on Idol ever...That girl is a ridiculous singer. I can't even put my brain...like, when you're a singer, you have to, like, go there in your head, like 'Can I go there, can I... oh I kind of know I can't do that.' She doesn't even have that. Like, she just goes anywhere she tries."
Steven Tyler: "The best singers have character. If you watch Reinhart up there, every bad comment she gets, it rolls right off, that's how good she is. The one thing I'm a little afraid of, America's been wrong before... Sometimes that character is a little bit to push people away."
Jessica Sanchez

Jessica Elizabeth Sanchez (born August 4, 1995) is an American singer-songwriter. She rose to prominence following her runner-up finish on the eleventh season of American Idol Her debut studio album, Me, You & the Music, peaked at number twenty-six on the US Billboard 200. In 2025, nineteen years after... read more

Jessica Sanchez is a happy and jubilant person from season 11 of American Idol in 2012. She should've won, but people thought Phillip Phillips was cute and had a contagious voice (with catchy songs that are easy to learn and love). However, Jessica was phenomenal in all her performances and was saved by the judges because of her pure talent!
She even auditioned for America's Got Talent when she was 8 or 7 years old, and she was great back then too. Her voice is so contagious and easy to love. She made it quite far in America's Got Talent, but I'm glad she still got a record deal because that's rare!
On American Idol, many contestants are young or can't fit into a record label, but Jessica made it. All in all, it's your decision where she ranks, but I just ask that when I revisit this site, Jessica Sanchez is at least in the top 4. She has a dash of Jennifer Hudson, the growl of Whitney Houston (rest in peace, Whitney), and hits high notes - not like the fifth octave, but the easy breezy mezzo-soprano high notes like Mariah. She also has Beyoncé's style and glow in her magnificent voice.
I know she'll be more prominent and famous than Julia Roberts! It's just the start of her career. I hope she joins lots of musicals in films. God bless.
Carrie Underwood

Carrie Marie Underwood (born March 10, 1983, in Muskogee, Oklahoma) is an American country singer, songwriter, and actress. She gained fame by winning the fourth season of American Idol in 2005.
Her debut album Some Hearts, released in 2005, produced five hit songs, including "Before He Cheats... read more

She has worked hard to pull off amazing performances on Idol and she is very successful after the show as well. She has grace and is very underrated. She hits high notes that Kelly Clarkson cannot even dream of.

I love her so much. She is an amazing country singer with star quality. And she seems to be down-to-earth and humble! Much better than Kelly Clarkson.

She should be number 1! She is the person who has had the most success after being on Idol! Powerhouse voice! Go Carrie!
Jordin Sparks

Jordin Brianna Sparks is an American singer, songwriter, and actress. In 2007, she rose to fame after winning the sixth season of American Idol. At age 17, she became the youngest winner in the series' history. She has since released several albums and appeared in films and television, including her... read more

She has an amazing, unique vocal range, and she's a true performer. When she is on stage and does her thing, nobody can say that she is not good enough because everyone knows that she has the talent and drive to be on top.

I really love her voice, especially when she sings Battlefield, Tattoo, and Permanent Monday.
She also had a good collaboration with Chris Brown in No Air and with Big Time Rush in Count on You.

Unbeatable vocal range... unfortunately, still untapped!
Jennifer Hudson

Jennifer Kate Hudson is an American singer, actress, and spokesperson. She rose to fame in 2004 as a finalist on the third season of American Idol, coming in seventh place. Hudson went on to win an Academy Award for her role in Dreamgirls and has since earned an Emmy, Grammy, and Tony Award, becoming... read more

Jennifer Hudson had the best voice from her season, and it is awesome to see her bringing down the house as Effie in Dreamgirls. Long overdue success for her.

By far one of the best voices of all Idol contestants. I would actually put her at number 2 after the great Miss Clarkson.

She is the definition of the American Idol, the epitome of perfection. I just love her.

The Newcomers

?
La'Porsha Renae

She has such a beautiful, soulful voice. Although she didn't win, she came in second place out of 190 contestants. That's extremely impressive.
Also, I found her story very touching.
?
Lauren Alaina

I have seen both Scotty McCreery and Lauren Alaina live, and Lauren is by far the better performer and voice.

The Contenders

Bo Bice
Colton Dixon

Colton Dixon is an American Christian singer-songwriter and musician from Murfreesboro, Tennessee. He gained national attention after finishing in seventh place on the eleventh season of American Idol in 2012. Since then, he has released several successful albums and is known for his faith-based music... read more

September and Piano Man were both incredible performances.

His song Never Gone is very good. He's become a great Christian rock artist.
Taylor Hicks

Taylor Reuben Hicks is an American singer and musician who rose to fame by winning the fifth season of American Idol in 2006. His soulful style and harmonica playing helped distinguish him from other contestants. After his win, he released multiple albums and performed in various stage productions, including... read more

Taylor is definitely my favorite Idol of all time. He was fabulous on the show and is amazing to see in person. I have been blessed to meet fellow fans over the years, and we have developed incredible bonds of friendship.
Taylor has achieved success on so many levels: as a writer, in a Vegas residency, on Broadway, on the Grease live tour, as a popular restaurant owner, and so much more. His efforts and generosity with charity projects have touched hearts in immeasurable ways. I hope Idol appreciates how Taylor helped to contribute to Idol's success in its most popular season ever.

A real musician back when Idol would not allow instruments. He had a great stage presence to sell a song. With the right guidance, I think he could have made it on radio, even though at the time everyone on radio sounded like voices squeezed through a computer. He's gone on to do what he does best: be a touring musician. He commands the stage and always is surrounded by a great band! Very unique voice. No one sounds like Taylor Hicks!
Ruben Studdard

Christopher Ruben Studdard is an American R&B, pop, and gospel singer. He rose to fame as the winner of the second season of American Idol. In December 2003, he received a Grammy Award nomination for Best Male R&B Vocal Performance for the song "Superstar."
Angie Miller

She has an amazing voice and she should have won that season. She is charismatic, talented, a nice person, and could be a very good role model. From the very first audition, I loved her. Her voice is very strong and she reminds me of Jessica Sanchez. They both have very strong voices and good personalities at a young age.

She should have won that year. For me, at least, she will go far and is the winner of this season!

She's not only beautiful but also has a powerful voice and message to share with the world.
Diana DeGarmo

Maybe not the best voice from her season, but she was always very polished for her age. She went on to have a career on Broadway. I actually believed she was better than Fantasia in the finale.
Pia Toscano

Thumbs up if you think she should have won that season!
Constantine Maroulis

One of the best male pop-rock singers I've ever heard. He should have come in at least 2nd or 3rd. His performance of "My Funny Valentine" is one of the best ever on Idol.
Kellie Pickler

Possibly one of the best personalities the show has ever seen.
Kris Allen

Kristopher Neil Allen is an American singer and songwriter from Conway, Arkansas. He gained national recognition as the winner of the eighth season of American Idol.
Before joining the show, he self-released an album titled Brand New Shoes in 2007. His coronation song "No Boundaries" and a cover... read more

Kris Allen is better than Adam Lambert. Just my opinion. Haha. I really love Live Like We're Dying, The Truth, and his latest song, The Vision of Love.

He's a brilliant musician who can match up with singers who have better vocals than him. A true dark horse!
Bucky Covington
Casey James

Casey is not just a great musician. He's a great person. He is a crazy-talented guitarist, an amazing songwriter, and a terrific singer. He pours every ounce of his energy into his performances and never disappoints. Yes, it's true he's easy on the eyes, but that's not what makes him so special.
In addition to his amazing gift, Casey is the most humble and down-to-earth artist out there. He remembers where he comes from and understands that his fans are what keep him going. He is generous, caring, and giving, actively involved with charities such as Children's Hospital. He appreciates his fans, ensuring he stays after shows to meet them.
Casey has overcome tremendous physical adversity, having been told he would never play guitar again after his accident. He is an inspiration and a role model to many. Although he didn't win American Idol, we all win by his participation in the show. Thank you to American Idol for bringing Casey James to the world. Thank you, Casey James, for making the world a little better for us.
Fantasia Barrino

Fantasia Monique Barrino, known professionally as Fantasia, is an American R&B singer, songwriter, and actress. She rose to fame as the winner of the third season of American Idol in 2004. Her debut single I Believe debuted at number one on the Billboard Hot 100.

Hands down my favorite Idol winner ever! I'll never forget her performance of Summertime. Iconic stuff right there.

Anyone that can bring Elton John to tears deserves all the accolades in the world.
Michael Johns

Michael, R.I.P., was the first male Idol I ever saw and immediately thought he could be a music superstar. He was robbed at only 8th place. Amazing personality, good looks, and what a voice! I miss him terribly!
Elliott Yamin

Efraym Elliott Yamin is an American singer who gained national attention by placing third on the fifth season of American Idol. He is best known for his hit single "Wait for You," which became a commercial success. Yamin has released several albums and continues to perform and record music.

Elliott has one of the most soulful voices of our time. He was a little lacking in stage presence, but I think the many times he shared a stage with Taylor Hicks helped pull him out of his shell. Some of the duets Elliott and Taylor have done in concert just bring the house down!

Definitely deserves to be in the top 10!
