->'''Milhouse:''' What are they saying?\\
'''Bart:''' I'm not sure.\\
'''Milhouse:''' I thought you said you could read lips.\\
'''Bart:''' I assumed that I could.
-->-- ''WesternAnimation/TheSimpsons'', "Lemon of Troy"

Characters being able to understand what others are saying by reading their lips. Usually an [[DisabilitySuperpower ability]] of deaf people, though anybody with good eyesight at least can have it. However, this ability is greatly overstated in fiction where the deaf are concerned, since it's fairly difficult to master and not all deaf people can do it, and even those that can are never perfect. In English, less than half of spoken sounds can be seen on the lips; the rest rely on the throat and tongue movements. That's how we get the joke about how "olive juice" looks exactly like "I love you." This trope is arguably similar to how so many blind people in fiction have SuperSenses, in that it introduces a character with a disability while minimizing the issues such a person would realistically face.

Can be used when two characters want to communicate silently. Alice wants to give Bob a message, so she mouths it to him. If PlayedForLaughs, then Bob will reveal that he can't read lips, making the whole thing pointless.

[[folder: Anime and Manga ]]

* ''GhostInTheShellStandAloneComplex'': in one episode, a Tachikoma reads the lips of the Major and Batou as a ShoutOut to ''Film/TwoThousandOneASpaceOdyssey''. Subverted because they know they're being watched and have their conversation via wireless communication with their cyberbrains and have a fake conversation for the Tachikoma to lip read [[spoiler: leaving them falsely reassured that The Major was merely chewing Bateau out for being too much of a DrillSergeantNasty and the Tachikoma weren't being decommissioned]].
* ''SoulEater'': Justin Law can read lips, which is good considering he has ear phones on most of the time.
** But he can't understand Shinigami (without removing his earphones) thanks to his mask.
* ''Manga/{{Gangsta}}'' features the deaf mercenary Nicolas, [[DisabilitySuperpower who can use his lip reading skills to understand what his targets are saying from a mile away.]]
* ''{{Manga/Golgo 13}}'': In "Melancholy Summer", Duke Togo reads the lips of a woman who's been waiting for her husband to return for six years. Unfortunately the man is Togo's target, and Togo reads his FamousLastWords through the scope as he's shot while calling out to her.

[[folder: Comic Books ]]

* In ''Comicbook/AvengersAcademy'' #1, Finesse reads Speedball's lips and learns that [[spoiler: the students are there because they are the most likely to become supervillains]].
* Comicbook/{{Superman}} used a viewer that gathers "light rays" to see past. As it's all light, superman had to use lipreading to see what was spoken. There was some oddities like blank talk bubbles from some people facing away from viewpoint. How would he know those people were speaking in first place?
* Occasional [[Comicbook/TheAvengers Avenger]] Echo can read lips as part of the implication that she's a deaf counterpart to Comicbook/{{Daredevil}}. However, the realistic limitations of this skill are still explored, since she has trouble communicating with heroes whose costumes cover their mouths like Comicbook/SpiderMan or Comicbook/IronMan, and she obviously can't respond to someone if her back is to them and she doesn't know they're talking.

[[folder: Film ]]

* In ''Film/TwoThousandOneASpaceOdyssey'', Dave and Frank lock themselves in a soundproof pod so they can safely talk about the project computer, HAL, who seems to be acting strange. It doesn't occur to them that HAL can read lips...

The latter movie foreshadows the skill by having a woman complain to her friend how Bronson's character never smiles. Bronson (who's across the room) picks that moment to smile at her, apparently disproving her point. She just says sourly that she knows he can read lips.
* [=McCall=] shows that he can use this in ''Film/{{Metro}}'' when he relays the conversation between his would-be partner and the chief to them after they had it behind soundproof windows. He gets use it again during the climax when he has to cover Scott during a hostage exchange.
* ''Film/{{Casino}}''. The FBI are shown using lipreaders to put surveillance on mafiosi who [[OvertRendezvous hold their meetings in the open]], paranoid as they are about bugs and wiretaps.

* In practice, lipreading is fairly difficult skill, with around 25-50% success on identifying words; the rest is using logic to fill in the blanks. Not all deaf people can lipread, as some would assume, and to top it off, it also varies depending on the individual deaf person's hearing level. ''And'' to add to mess, it also depends on the person speaking, especially if the person mumbles, has a strong accent, or has facial hair that covers the lips. Generally, deaf people have a much easier time understanding someone they know personally--family and friends--than complete strangers.
* At least one deaf basketball team has won this way, as the rival team spoke their plan out loud since they weren't worried about being overheard, unaware that the deaf players could also read lips.
