George Costanza

George Louis Costanza is a fictional character in the American television sitcom Seinfeld (1989–1998), played by Jason Alexander. He is a short, stocky, balding man who struggles with numerous insecurities, often dooming his romantic relationships through his own fear of being dumped. He is also remarkably lazy; during periods of unemployment he actively avoids getting a job, and while employed he often finds ingenious ways to conceal idleness from his bosses. He is friends with Jerry Seinfeld, Cosmo Kramer, and Elaine Benes. George and Jerry were junior high school friends (although in "The Betrayal", Season 9, Episode 8, George says the two have been friends since fourth grade) and remained friends afterward. George appears in every episode except "The Pen" (third season).

The character was based on Seinfeld co-creator Larry David but is surnamed after Jerry Seinfeld's real-life New York friend, Michael Costanza. Alexander reprised his role in an episode of Comedians in Cars Getting Coffee, reuniting with Jerry Seinfeld and Wayne Knight (also reprising their roles as Jerry and Newman, respectively).
