A character whose defining characteristic is that he is ridiculously forgetful. Usually played for comedy, this trope does ''not'' cover characters with Alzheimer's or brain injuries that legitimately impair their short-term or long-term memory.

Compare AbsentMindedProfessor. For showrunners assuming their audience's memory is this bad, see ViewersAreGoldfish.

[[folder:Comic Books]]
* Ira West (Iris' [[spoiler:adoptive]] father, Wally's grandfather) in ''Franchise/TheFlash''. In his first appearance, he was told Barry Allen's SecretIdentity and helped create his super-compressed costume, but had forgotten all about it the next day.
* Quinton Zempfester from ''ComicBook/ThievesAndKings''.
* Senilo in the Swedish superhero spoof ''Kapten Stofil''. His superpower is being [[WhatKindOfLamePowerIsHeartAnyway incredibly forgetful]]. While generally useless, this sometimes allow him to perform marvelous feats as long as they occur off-panel and he doesn't remember what he did. ("How did you get free?!" "I haven't the foggiest. Where are we?")

[[/folder]]

[[folder:Films -- Animation]]

-->'''Dory:''' I suffer from short-term memory loss. It runs in my family. Well, at least I think it does... Where ''are'' they?
[[/folder]]

[[folder:Films -- Live-Action]]
* ''Film/TheAbsentMindedProfessor'' (or, indeed, any AbsentMindedProfessor). The original movie begins with the Fred [=MacMurray=] character ''forgetting his own wedding!''
* Uncle Billy in ''Film/ItsAWonderfulLife'': Besides his big blunder toward the end of the film, an earlier scene shows him with reminder strings tied on several different fingers, indicating that he is generally prone to forgetfulness.
[[/folder]]

[[folder:Literature]]
* "Biffy" Biffen from the ''Literature/JeevesAndWooster'' stories, who has found the girl of his dreams, but ''can't remember her last name!'' Also applies to the [[Series/JeevesAndWooster TV show]].
* Another Creator/PGWodehouse example: Lord Emsworth of ''Literature/BlandingsCastle''.
* [[AbsentMindedProfessor Professor Plum]] from the ''TabletopGame/{{Clue}}'' book series.
* Mr. Forgetful from the ''Literature/MrMen'' series. In his book, he even has to memorize a message (and, being Mr. Forgetful, gets the message wrong, of course).
-->''' Mr. Forgetful:''' There's a goose asleep in the rain!
::The original message was "There's a sheep loose in the lane."
* Neville Longbottom of ''Literature/HarryPotter'' fame, long before his MemeticBadass days, was this for the first four (and part of the fifth) books. It's implied that he was this because of his lack of self-confidence and drive to be better. Or it could be due to the [[spoiler:Memory charm he received as a child to erase his traumatic memories of watching his parents be tortured into insanity.]]
[[/folder]]

[[folder:Live-Action TV]]
* The ''Series/SaturdayNightLive'' sketch "Mr. Short-term Memory", with Creator/TomHanks.

[[folder:Video Games]]
* Koishi of ''VideoGame/{{Touhou}}'' had become this as a side effect of her completely sealing her ability to read any minds, including her own. By ''Hopeless Masquerade'', she mentions that she tends to forget everything now, so she's surprised that she could still remember [[spoiler:the Mask of Hope that she found some time ago]].
* Gaboonga from ''VideoGame/WonderlandAdventures'' frequently forgets his own name.
[[/folder]]

[[folder:Web Animation]]
* ''WebVideo/UltraFastPony'' has Rose, in her one scene from the episode "So Random!"

'''Rose:''' Sorry about that, I've got a very bad memory.\\
'''Pinkie:''' Oh, don't worry. I'm sure we'll get that fixed one day.\\
'''Rose:''' Get what fixed?\\
(''beat'')\\
'''Rose:''' 'Allo, Pinkie Pie!\\
'''Pinkie:''' Goodbye, Rose.

[[folder:Web Comics]]
* Jade Harley of ''Webcomic/{{Homestuck}}'' starts out somewhat like this, hence why her fingers are covered in reminder strings.
* Tyler from ''Webcomic/MorphE'' is so forgetful that he needs to keep a journal for reminders.
* In ''Webcomic/CityFace 2'', City Face forgets what Torus said, mere seconds after she said it.

[[/folder]]

[[folder:Web Original]]

[[folder:Western Animation]]

* The ''WesternAnimation/CourageTheCowardlyDog'' episode, "Bride of the Swamp Monster" had a swamp monster's girlfriend (also a swamp monster) who forgot things instantly. She even says that she never got his letters because every time she got off work she forgot where she lived.
* Mr. Scatterbrain from ''WesternAnimation/TheMrMenShow''.
* This is the main trait of Lily the fox on ''WesternAnimation/TimothyGoesToSchool''. It's not played for comedy, though, so much as AnAesop that she is working to get better about it.
* On ''WesternAnimation/YoungJustice,'' [[EnfantTerrible Klarion]], since he's a [[HumanoidAbomination Lord of Chaos]] whose mind works differently than a human's. Upon being told that [[MadScientist T.O. Morrow]] is in a coma, he pauses to ask "Did I know that already?" WordOfGod also noted that while everyone in [[OmniscientCouncilOfVagueness the Light]] knew about [[spoiler:Black Manta]] being Kaldur's father, "whether Klarion remembers is a legit question."
* Patrick on ''WesternAnimation/SpongebobSquarepants'' is so stupid he'll sometimes forget things in seconds. Like when he and [=SpongeBob=] were hiding out in the desert and he decided to eat his only food, a chocolate bar, in one go and then immediately forgets he ate it.
* ''WesternAnimation/AdventureTime'': Lumpy Space Princess can be ridiculously forgetful at times. In "Video Makers" after Jake tells her they're filming a food fight scene she immediately forgets they're filming a scene and gets mad when Peppermint Butler throws food at her.
