Smartest Harry Potter Characters


The Top Ten

1 Hermione Granger Hermione Granger

I love Hermione she is so smart harry and Ron would be dead if they didn't have her

Hermione Granger is my favourite character because she is smart. If it wasn't for her, Harry Potter and Ron Weasley would be dead in the first book.
In book 1 she was the one who solved the Snape's obstacle. In the second book she found out what the monster in the chamber of secrets was and that helped Harry defeat the Basilisk and save Ginny Weasley. In the third book she used a timeturner just so she could attend extra classes, then she realised that their defense Against the Dark arts teacher Remus Lupin was a werewolf and then used the timeturner with Harry to save Sirius Black and Buckbeak the Hippogriff. In the fourth book she wants to free all the house elves in Hogwarts kitchen the goes to the Yule Ball with Dumstrang Triwzard Champion Viktor Krum and at the end she figures out that Rita Skeeter is a unregistered Animigi. In the fifth book she helps Harry run Dumbledore's Army once Umbidge don't allow them to do proper defense Against the Dark Arts then takes part in the ...more

Hermione granger is my favorite because she is so smart. She could probably defeat Voldemort!

She is so cool - StarGirl23

2 Albus Dumbledore Albus Dumbledore Professor Albus Percival Wulfric Brian Dumbledore is a fictional character in J. K. Rowling's Harry Potter series.

I think Dumbledore should be first. Hermione may be smart, but she is dumb compared to Dumbledore. After all, it was he who discovered Voldemort's secret, and he who discovered the locket, things Hermione never did.

He is smarter

He should be the first! He is so much better and smarter than the muggle born Hermione Granger!

Dumbledore is the smartest person on Harry potter he knows things that other people do not know

3 Severus Snape Severus Snape Severus Snape is a fictional character in J. K. Rowling's Harry Potter series. He is characterised as a person of great complexity, whose coldly sarcastic and controlled exterior conceals deep emotions and anguish.

He was the best and most interesting character of the series.

I love him


Snape should be higher on the list. He created his own spells! - Ravenclaw12

4 Luna Lovegood Luna Lovegood Luna Lovegood was a witch, the only child and daughter of Xenophilius and Pandora Lovegood. Her mother accidentally died while experimenting with spells when Luna was nine and Luna was raised by her father, editor of the magazine The Quibbler, in a rook-like house near the village of Ottery St Catchpole more.

All these people are giving these long, inspiring speeches. This is me: Luna is cool. (Lol)

People seem to focus more on the movie Luna.
Luna in the books was more dotty. With her beliefs in imaginary creatures like the Crumple-Horned Snorkack.
Her lion hat was really a like a head of a lion which roared like a lion. But they changed it in the movies.
The nargles she believed in were actually what she believed was something that mistletoe was infested with.
But no Luna isn't dumb or she wouldn't be a Ravenclaw she can answer the questions to enter the common room and she made a hat with a lions head which roared like one and her mother used to experiment and the experiment probably just exploded maybe a dangerous potion I don't know.

She's smart in her own way. I would say that she's more wise rather than smart.

She not book smart but life smart

5 Voldemort Voldemort Lord Voldemort is a fictional character and the central main antagonist in J. K. Rowling's series of Harry Potter novels. Voldemort first appeared in Harry Potter and the Philosopher's Stone, which was released in 1997.

Tom Riddle aka Voldemort was known as the smartest student at his time at Hogwarts and everybody knew it. - ParasN2000

Voldemort isn’t actually smart, who could have realized that he couldn’t kill Harry in the first book instead of trying to kill him till the end of the Harry Potter series if he wouldn’t be talking for so long and just get to the killing part.

6 Remus Lupin Remus Lupin

Being, 'smart,' doesn't necessarily mean Ravenclaw- worthy. He was indeed smart, but there is more to Ravenclaw. Does he love learning? Does he value knowledge above all? Does he think outside the box? If so, maybe he just values bravery more,

He was the brains of the marauders. He was the brains of the Order of Phoenix. Belonged in Ravenclaw but put in Gryffindor for plot reasons.

7 Harry Potter Harry Potter Harry James Potter is the title character of J. K. Rowling's Harry Potter series. The majority of the books' plot covers seven years in the life of the orphan Potter, who, on his eleventh birthday, learns he is a wizard.

Harry is clever I love him

Only haters of the Harry Potter books think he is an idiot.

Harry potter Rocks

Harry is sort of an idiot

8 Gellert Grindelwald

Grindelwald had as much magical knowledge as Dumbledore. That about says it all.


He was also a seer. Dumbledore and Grindelwald's knowledge was equal. He was also the only man ever to manipulate Dumbledore.

Grindelwald was every bit as brilliant as Dumbledore.

9 Lily Evans

As per the pensieve memories and Horace Slughorn, Lily was a brilliant student with a knack in potions and apparently charms as well. Plus she was cheeky, had a smart answer at the tip of the tongue. She 'earned' the slug club spot without any familial connection. This must mean something. She was a 'full time fighter' in the Order as well. And she thrice defied Voldemort alongwith James. She was definitely smart and kind.

10 Sirius Black Sirius Black

Sirius is really smart, escaping Azkaban and then being able to hide from the Dementors while also looking for Harry takes lot's of intelligence, it isn't as easy as it sounds

Yep agreed but why isn't he in the top 10?

You should be smart to escape Azkaban without any help. He was even an animagus in just his 5th year. McGonagall described him as one of the cleverest students (along with James). He was even had a bit of detective skill in him.

The Newcomers

? Quirinus Quirrell Quirinus Quirrell

He got two trolls in Hogwarts without anyone noticing.
He taught two classes (Remember no one can teach defense Against The Dark Arts for more than one year till Voldemort died)
He was a Ravenclaw.

? Cedric Diggory Cedric Diggory

Little was known about him but he is not stupid. If it had been the three champions we would've seen more of Cedric's smartness.

The Contenders

11 Professor Horace Slughorn
12 Ron Weasley Ron Weasley Ronald Bilius "Ron" Weasley is a fictional character in J. K. Rowling's Harry Potter series. His first appearance was in the first book of the series, Harry Potter and the Philosopher's Stone as the best friend of Harry Potter and Hermione Granger.

Its like people want to ignore everything that happened in deathly hallows. During the battle, he figured out things that most people could not even understand (including hermione granger, who is the brightest witch of her age). It is obvious that he is extremely clever but only when it comes to the things he is interested in, like chess. He is not great at studies because he doesn't care enough. If he did, he'd be one of the best in his year.

Hermione should get some of the credit for Ron's rare smarts. She taught him wingardium leviosa and some other things. Normally, he's just an idiot.

If it wasn't for Ron, the Hufflepuff cup wouldn't have even been destroyed because he is the one who came up with the idea to use the basilisk's fang in the first place.

13 Minerva McGonagall Minerva McGonagall

Why is she so low? - lessi

Hermiones dumb

McGonagall should be 2nd or 3rd! She is so wise and is Dumbledore’s right hand. Hermione is just book smart, McGonagall is book smart and wise.

14 Scorpius Malfoy Scorpius Malfoy

Why is he all the way down here? Scorpius is SMART!


Scorpius is REALLY REALLY SMART! Smart as Hermione is. Or maybe he is smarter than her. HE SHOULD'VE BEEN 1st,2nd or 3rd.

VOTE FOR SCORPIUS PLEASE. I love you, Scorpius ;Don't worry you are smart. XOXO

15 Draco Malfoy Draco Malfoy Draco Lucius Malfoy is a character in J. K. Rowling's Harry Potter series. He is a student in Harry Potter's year belonging in the Slytherin house.

Why is he all the way down here? He must have been smart to figure out the vanishing cabinets, and he was able to figure out that Harry was spying on him.Hermione is still the smartest though.

my angel

What idiot put him this low on the list? Are you people forgetting that he repaired the vanishing cabinet,figured out that Harry was spying on him on the train, and made a snake shoot out of his wand,which means he pays attention in class? Honestly,anti-Slytherins probably made this list.Just because he’s evil doesn’t make him stupid. - Slytherin nerd

16 Alastor Moody Alastor Moody
17 James Potter
18 Ginny Weasley Ginny Weasley

Ginny is smarter than Ron. Hands down.


Ginny is smarter than ron in many ways! ggrrr

19 Neville Longbottom Neville Longbottom
20 Arthur Weasley Arthur Weasley
21 Regulus Black

Yes... he was the first person to ever discover Voldemort's secret and he was smart enough to find the locket... although he didn't live to see it destroyed...

He discovered Voldemort's horcruxus when he was 18 and stealed one. He deserves a place on the list.

22 Rowena Ravenclaw

The creator of Ravenclaw deserves a better position in the smartest characters in Harry Potter

23 Dudley Dursley Dudley Dursley

Well the main character, Harry was called an idiot so let's add Dudley to the list.

;-; He isb not smart.

24 Barty Crouch Jr.

He is dumb

Well, he was the impostor of Alastor Moody in the 4th book(and movie :)) So, it was actually him, who knew everything for the three tasks.

25 Kreacher
26 Cho Chang

She's in Ravenclaw.

27 Bellatrix Lestrange

She’s easily top 10 maybe top 5
Rob Ginny neveille cleverer than her
Gimme a break

28 Filius Flitwick
29 Kingsley Shacklebolt


30 Nymphadora Tonks
31 Alecto Carrow

I think he is the most clever, and nicest

32 Narcissa Malfoy
33 Vincent Crabbe
34 Gilderoy Lockhart

Smart but lazy.
Tricked people till Dumbledore knew many of them and gave Lockhart his punishment, also no one else was around to teach the job.

He was smart but was lazy and defeated by his own sword

35 Gregory Goyle

When you call Harry an idiot add Goyle.
Oh and Harry did pretend to be him under Polyjuice for an hour.
