* SugarWiki/AwesomeMusic: The soundtrack. The Moldy Peaches' "Anyone Else But You" is now [[SongAssociation inseparable]] from the movie.
* BaseBreakingCharacter: Vanessa is either a [[TheWoobie Woobie]] who wants to be a mother or a [[LeeroyJenkins reckless]], [[ItsAllAboutMe self-centered]] {{Jerkass}} who doesn't have the emotional fortitude or the know-how to do so. There's seemingly no gray area; people who see the film are either with her or against her.
* GeniusBonus: While the movie mentions that Juno's named after the Roman goddess Juno, it doesn't mention that one of the main domains of the goddess is childbirth.
* HilariousInHindsight: After Ellen Page came out, it is ironic that Juno suggested giving the baby to "a couple of nice lesbos"
%%* HypeAversion
* LoveItOrHateIt: Less the movie so much as the dialogue. Its quirkiness is either a huge part of its charm or deeply obnoxious.
* MisaimedFandom: Not by a whole lot, but pregnancy fetishists have a great admiration for this movie, especially the scene in which Juno enthusiastically rolls up her shirt for Vanessa at the mall.
** And then there's those that use the film as a tool to promote pro-life or pro-choice arguments with regards to abortion, when WordOfGod indicates that the film was meant to be neutral on the subject.
* NoYay: Mark and Juno, when they dance together.
** Mark and Juno in general. More than one viewer might have thought this movie was about to take a turn into ''much creepier'' adulterous MayDecemberRomance territory with the way Mark kept being so friendly to Juno and the way she kept spending time alone with him, but no, that's not what happens.
* RonTheDeathEater / TheScrappy: Vanessa is subject to this by haters of the film.
* {{Squick}}: Oh, GOD. Those [[UnusualEuphemism PORK SWORDS]]!!!
* WhatDoYouMeanItsNotPolitical: In vain with MisaimedFandom above, there are pro-life activists who use the film as a tool against abortion, although Diablo Cody and Ellen Page are both pro-choice.
* TheWoobie: Depending on who you ask, Vanessa.
