- (To his students) "I'm Kakashi Hatake. I have no desire to tell you my likes and dislikes… My dreams for the future… Hmm… As for my hobbies… I have lots of hobbies…"
- (To his students) "In the ninja world, those who break the rules are trash, that's true, but those who abandon their comrades are worse than trash."
- (To Sasuke) "I won't allow my comrades to die. I'll protect you with my life. Trust me."
- (To Naruto) "I can see where a thing like that would be hard to accept… but it's a fact you'll have to live with. This probably won't be the last time we run into a kid who's both younger than you… and stronger than me."
- (To his students) "Sorry I'm late, I'm afraid I got lost on the path of life.
- (To Orochimaru) "I don't care if you are one of the legendary Sannin, the great shinobi of legend, I swear take one more step towards Sasuke and one of us will die here!"
- (To Yūgao, about Obito's name engraved in the Memorial Stone) "This place makes me think about the mistakes I've made in the past… and I've made so many of them."
- (Looking at the statues of Madara and Hashirama in the Valley of the End) "Like the fate of the two who founded the village of Konoha… Naruto and Sasuke… your fates are like theirs."
- (To Kakuzu) "The next generation will always surpass the previous one. It's one of the never-ending cycles in life."
- (To Pain) "The people from this village are different from your average village. Even if it means dying, there's not a single one of us, who would sell out a comrade."
- (To Sakumo) "Regardless of what happened, you did the best you could. I understand that now… you broke the rules for all our sakes - I'm proud of you now…"
- (To Sasuke) "No matter how far Orochimaru fell, he still loved him… Now I know how the Third Hokage felt.
- (To the Third Division) "Look, it takes a lot to get me worked up, but this time my boiling point's as low as it's ever been. The "Copy Ninja" Kakashi, the man who copied one thousand techniques is about to go on a rampage!"
- (To Obito) "I'm just a piece of trash… but there are things I learned. The hole in your heart is something other people can fill. If you reject your friends' feelings and this world… just because something didn't go as you wished, no one will ever come to you. And so that hole won't be filled either, if you just run away without doing anything people won't do anything for you either… As long as you don't give up, you can still be saved!"
- (To Obito) "In the ninja world, those who break the rules are trash. However, those who abandon their comrades are worse than trash. And the ones who abandon their friends' feelings are even worse than that. I won't get rid of your past feelings, even if it's you who's refusing them."
