Jeff "Joker" Moreau is a character from BioWare's Mass Effect franchise. In the original Mass Effect video game trilogy, he is the pilot in command of the Normandy-class SR, a highly advanced series of spacecraft with stealth capabilities which serve as the base of operations for the player character, Commander Shepard. In Mass Effect 2, Joker briefly becomes a playable character when the Normandy is invaded and the majority of its crew captured by hostile forces. Outside of the video game series, Joker appears as the central character of the 2013 comic book, Mass Effect: He Who Laughs Best, which explores the backstory behind how he became the pilot of the Normandy. He is voiced by American actor Seth Green, who was given a level of creative freedom to improvise the character's dialogue during recording sessions.

The character's nickname alludes to his characterization as a sarcastic foil to other characters who interact with him. Joker has been recognized as one of the most notable examples of disability representation in video game medium. Aspects of Joker's characterization, such as his depiction as a skilled pilot who excels in spite of his limited mobility caused by a genetic disorder colloquially known as brittle bone disease, as well as his defensive attitude towards other characters who engage him in a conversation about his condition, has been the subject of scholarly analysis published in academic journals.
