Top 10 Fictional Characters Voiced by Children

More often than not in animation, fictional children and characters of an early prepubescent age are voiced by adult female voice actresses.

However, on those somewhat rare occasions when the characters are actually voiced by young actors and actresses of a similar age, we get this list of the Top Ten Fictional Characters Voiced by Children. (See what I did there?)

Feel free to add any characters I may have missed.

The Top Ten

Dash Parr (The Incredibles)

Dash Parr is a fictional character in The Incredibles franchise created by Pixar. He is the super-speed son of Mr. Incredible and Elastigirl. Dash appears in both The Incredibles (2004) and its sequel Incredibles 2 (2018), where he uses his powers to help his family fight crime.

The energetic, super-speedy son of Bob Parr/Mr. Incredible in the 2004 animated Pixar film, The Incredibles, is voiced by 11-year-old Spencer Fox in the original film and a similarly aged Huck Milner in the 2018 sequel.
Charlie Brown (Peanuts)

Boo (Monsters, Inc.)

Mary Gibbs, born on October 5, 1996, is an American voice actress. She is best known for voicing Boo, the curious and fearless toddler in the 2001 Pixar animated film Monsters, Inc. The character Boo is the film's tritagonist and is central to the story's emotional core.

Voiced by 2-year-old Mary Gibbs at the time, daughter of storyboard artist Rob Gibbs, the most notable behind-the-scenes fact about her recording is that she was unable to sit still in the recording booth. They followed her around the studio with a microphone to record her lines.
Young Simba (The Lion King)

Simba is a fictional character in Disney's The Lion King franchise. He made his debut in the original 1994 animated film The Lion King and went on to appear in its sequels, The Lion King II: Simba's Pride (1998) and The Lion King 1½ (2004).... read more

The main playable protagonist of the long-running Disney/Square Enix video game series, Kingdom Hearts, is voiced by 14-year-old Haley Joel Osment at the time and continues to be voiced by him as they both age. Even as an adult, his older voice surprisingly still matches his character perfectly.
Gumball Watterson (The Amazing World of Gumball)

Gumball Watterson is a twelve-year-old blue cat known for causing mischief around town due to his imaginative and often reckless behavior. He is egotistical and a veteran snarker. Despite this, Gumball has a big heart and can be surprisingly selfless.... read more

Oliver is an English-language Vocaloid developed by PowerFX Systems AB in collaboration with VocaTone. His voice was recorded from a British choirboy and he was released for the Vocaloid 3 engine in December 2011. Oliver is popular for his youthful and classical vocal tone.

A 12-year-old young vocaloid released in 2011, voiced by a 13-year-old British boy at the time.

Kaai Yuki (Vocaloid)

Kaai Yuki is a child Vocaloid character produced by AH-Software Co. Ltd and released originally for Vocaloid 2. Her voice is provided by a real elementary school student, making her one of the few Vocaloids with a child's voice. Kaai Yuki was released on December 4, 2009.

The Contenders

Pinocchio (Pinocchio)

Voiced by Dickie Jones, who was 11 years old when he voiced Pinocchio. Disney rejected the idea of Pinocchio being voiced by an adult and insisted that the character be voiced by a real child.
Scootaloo (My Little Pony: Friendship Is Magic)

Voiced by Madeleine Peters, who was around 14 at the time of her casting.
Clyde McBride (The Loud House)

Clyde McBride is a fictional supporting character in the animated series The Loud House. He is Lincoln Loud's best friend, known for his energetic personality and love of gadgets.
Ike Broflovski (South Park)

Ike Broflovski is a recurring character in the animated adult television series South Park. Ike is Kyle Broflovski's adopted little brother from Canada. He is known for his distinctive Canadian-style animation and often plays a humorous role in the series.

Voiced by various children, including Trey Parker's daughter.
Ponyo (Ponyo)

Voiced by Noah Cyrus, younger sister of Miley Cyrus, who was 8 when she voiced Ponyo in the English dub.
Jeff Randell (Clarence)

Sean Giambrone was 15 at the time he voiced Jeff, while most, if not all, of the other kids were voiced by adults. This explains why his voice became more creaky with each season. Let's just say puberty was not kind to this kid.
Anne-Marie (All Dogs Go to Heaven)
Aisling (The Secret of Kells)

Aisling is a secondary character in the 2009 animated film The Secret of Kells. She is a forest spirit who helps the young protagonist, Brendan, on his journey to complete the Book of Kells. Aisling is voiced by Christen Mooney and is noted for her ethereal presence and protective nature.

I feel like Cartoon Saloon's movies earn mad respect for the amazing child voice acting. Christen Mooney's singing was just perfect, and she even wrote her song too. Plus, they help keep 2D animated movies alive!
Norman Babcock (ParaNorman)
Kubo (Kubo and the Two Strings)
Eggs (The Boxtrolls)
Koda (Brother Bear)
Agnes Gru (Despicable Me)
Coraline Jones (Coraline)

Amazing character voiced by the amazing Dakota Fanning when she was a child. What more could one ask for?
Greg (Over the Garden Wall)
