- “I'm highly logical which allows me to look past extraneous detail and perceive clearly that which others overlook.”
- ―Hermione
- “Now - if you two don't mind - I'm going to bed. Before either of you come up with another clever idea to get us killed, or worse, expelled.”
- ―Hermione to Ron and Harry after their encounter with Fluffy
- “Nobody in my familys magic at all, it was ever such a surprise when I got my letter, but I was ever so pleased, of course, I mean, it's the very best school of witchcraft there is, I've heard — I've learned all our course books by heart, of course, I just hope it will be enough —”
- ―Hermione
- “Well, the Sorting Hat did seriously consider putting me in Ravenclaw during my Sorting, but it decided on Gryffindor in the end.”

- “Hermione Granger: Has anyone seen a toad? Neville's lost one.
Ron Weasley: We've already told him we haven't seen it.

- “They would have felt sorry for Hagrid when the time came for him to say good-bye to Norbert if they hadn't been so worried about what they had to do. It was a very dark, cloudy night, and they were a bit late arriving at Hagrid's hut because they'd had to wait for Peeves to get out of their way in the entrance hall, where he'd been playing tennis against the wall. Hagrid had Norbert packed and ready in a large crate.”
- ―Harry and Hermione prepare to drop Norbert off with Charlie's friends
- “Brilliant. This isn't magic — it's logic — a puzzle. A lot of the greatest wizards haven't got an ounce of logic, they'd be stuck in here forever.”
- ―Hermione
- “Of course not. Everything we need is here on this paper”
- ―Hermione
- “Well, if you two are going to chicken out, fine. I don't want to break rules, you know. I think threatening Muggle-borns is far worse than brewing up a difficult potion. But if you don't want to find out....”
- ―Hermione breaking school rules in an attempt to catch the Heir of Slytherin
- “It's called a Time-Turner, and I got it from Professor McGonagall on our first day back. I've been using it all year to get to all my lessons. Professor McGonagall made me swear I wouldn't tell anyone. She had to write all sorts of letters to the Ministry of Magic so I could have one. She had to tell them that I was a model student, and that I'd never, ever use it for anything except my studies.... I've been turning it back so I could do hours over again, that's how I've been doing several lessons at once, see?”
- ―Hermione explaning to Harry her use of a Time-Turner during her third year
- “Harry, I don't understand what Dumbledore wants us to do. Why did he tell us to go back three hours? How's that going to help Sirius?”
- ―Hermione to Harry
- “You know, house-elves get a very raw deal! It's slavery, that's what it is! That Mr Crouch made her go up to the top of the stadium, and she was terrified, and he's got her bewitched so she can't even run when they start trampling tents! Why doesn't anyone do something about it?”
- ―Hermione beginning her campaign for the better treatment of house-elves
- “Well, of course you haven't. I've only just started it.”
- ―Hermione to Ron
- “No, you see... Rita Skeeter — is an unregistered Animagus. She can turn — into a beetle.”
- ―Hermione Granger exposing Rita's abilities as an Animagus
- “Oh, Rita hasn't written anything at all since the third task. As a matter of fact. Rita Skeeter isn't going to be writing anything at all for a while. Not unless she wants me to spill the beans on her.”
- ―Hermione discovered that Rita Skeeter was an unregistered Animagus
- “No, I told her to keep her big fat mouth shut about you, actually. And it would be quite nice if you stopped jumping down Ron and my throats, Harry, because if you haven't noticed, we're on your side.”
- ―Hermione
- “Harry, don't you see? This... this is exactly why we need you... We need to know what it's really like... facing him... facing V-Voldemort. Well... think about it. Please?”
- ―Hermione to Harry
