->''"You just show that your first-person narrator was actually in an insane asylum and then OH MY GOD, did it actually happen? Who can say? Here, I can say. It didn't happen because your narrator was just no good. Listen. Never lend an unreliable narrator money."''

In most narratives, there's an element of trust that the [[{{Narrator}} person telling you the story]] is telling the truth, at least as far as they know it. This trope occurs when that convention is discarded. The narrator's facts contradict each other. If you ask them to go back a bit and retell it, the events come out a little differently. It can be like dealing with a [[HonestJohnsDealership used-car salesman]] -- there's a real story in there somewhere, but you're left to piece it together through all the lies, half-truths, and mistruths.

Reasons for the unreliability vary. Sometimes the narrator is a guilty party and is trying to mislead the audience as well as the other characters. If the narrator is insane, it's ThroughTheEyesOfMadness. A consistent and sincere testimony may prove Unreliable if coming from a perspective of personal bias, or conclusions drawn from incomplete observation. If the narrator has honestly misunderstood what's going on due to naivete, inexperience, or just lack of information, it's InnocentInaccurate.

As an author, this is a difficult trick to pull off. It is a lot easier to tell a straight story than it is to deliberately mislead the audience, never mind that it violates the traditional assumption that ViewersAreMorons. And there's always a risk of attracting MisaimedFandom.

One common technique is to use a FramingDevice, so that the narrator is presented as a character in the frame story, to emphasize that he is not actually the author. Another, even trickier method, is the LiteraryAgentHypothesis, where the narrator is supposedly relating things that happened in RealLife. Multiple unreliable narrators results in RashomonStyle. If it's a visual medium and the picture contradicts the narration, it's an UnreliableVoiceover. This can also be used as a trick in [[{{Advertising}} commercials]], to evade claims of false advertising by having an unreliable character do the talking.

First-person stories and third-person-limited stories are candidates for two levels of the UnreliableNarrator. First, a well-written story would have the InnocentInaccurate version, simply because the narrator shouldn't provide any information that the viewpoint character doesn't have, and in a more-difficult version, may not be able to provide information he has because the character hasn't the vocabulary or the necessary background knowledge. Second, the narrator sometimes refuses to tell us what the viewpoint character knows or sees at a critical junction.

In video games and other interactive works, an unreliable narrator can maintain immersion while dismissing the character losing numerous VideoGameLives as poor memory or wandering thoughts, or even while drawing attention to [[WhatTheHellHero uncharacteristic actions]] or [[ButThouMust exhaustion of options]]. This does require more effort on the designers to identify potential plot branches and the consequences of '''all''' of the player's possible input at every critical moment.

UnreliableExpositor is a variant with less than credible {{exposition}} from specific characters, as opposed to narrators of the whole story. Contrast MaybeMagicMaybeMundane where the evidence is reliable but insufficient, and InfallibleNarrator, when the narration of the character is far more accurate than the character's capabilities.

This can also be a source of humour for the work, too.

Note that this is specifically for narrators within the work. When it's the author that's lying, that's LyingCreator. When the author simply can't make up his mind, that's FlipFlopOfGod.

Note: as this is often a particularly subversive [[TheReveal Reveal]], '''REALLY BIG spoilers''' ahead, especially in the Literature section. See also RashomonStyle, UnreliableVoiceover, and SelfServingMemory.
