->'''Q:''' You hit me! Picard never hit me!
->'''Sisko:''' I'm ''not Picard!''
-->-- ''Series/StarTrekDeepSpaceNine'', "Q-Less"

Sometimes, there's a character that does things differently than others would expect of another character, such as when the TyrantTakesTheHelm or there's a BaitAndSwitchTyrant. He will be called out on it, being told that the other character would not behave this way. To that, he will simply answer with the StockPhrase "I am not him". He is not that other guy, and everyone will have to learn to accept that.

IAmNotMyFather is a family-centered SubTrope.

Compare IAmWhatIAm.

Not to be confused with IAmNotShazam, IAmNotSpock, IAmNotLeonardNimoy, IAmNotWeasel or AccidentalMisnaming. This is not the inversion of ActuallyIAmHim, either.

* In ''Literature/AmericanGods'', Mr. Wednesday is the American incarnation of Odin ("Wednesday" comes from "Wotan's Day," "Wotan" being another version of "Odin")and is a real JerkAss [[spoiler: not to mention the BigBad of the novel]]. Shadow, the protagonist, later meets the Scandinavian Odin who is a rather more likable BoisterousBruiser, who explains that Wednesday was him, but he was not Wednesday.

* The page quote is from the ''Series/StarTrekDeepSpaceNine'' episode "Q-Less", the only episode to feature Q from ''Series/StarTrekTheNextGeneration''. Q and Sisko are in a 20s-style boxing ring, and Q is trying to get Sisko to fight. After a while, Sisko finally punches Q down, much to his surprise. This was to help differentiate Sisko from the previous ''Franchise/StarTrek'' captains, particularly Picard.
* ''Series/{{Monk}}'': In one of Natalie's first episodes, Monk complains that Sharona always paid for the wipes. Natalie tells Monk, "I am not Sharona." It came across as a weak cover for the fact that Natalie was a SuspiciouslySimilarSubstitute for Sharona, and that the episode was originally written for Sharona.
* Rossi from ''Series/CriminalMinds'' gets a line similar to this in one of his early episodes after he replaces Gideon.
* On ''Series/LawAndOrder'', Jack [=McCoy=] catches the corrupt Governor Donald Shalvoy in a prostitution scandal that has also led to murder. He makes a deal with the Governor not to indict him if Shalvoy testifies against his wife. Executive ADA Michael Cutter adds another twist after [=McCoy=] leaves the room: Shalvoy immediately steps down from office. When Shalvoy protests that this wasn't part of his deal with [=McCoy=], Cutter says, "I'm not Jack [=McCoy=]."
* ''Series/{{Mash}}'': When Col. Potter took over, one of the first things he does is start rearranging the office. When Radar points out that Col. Blake liked a certain filing cabinet against one wall, Potter states "Blake's gone. I'm in command now" and has Radar move the filing cabinet to a different wall.
