Jerome "Jerry" Seinfeld is the protagonist of the American television sitcom Seinfeld (1989–1998). The straight man among his group of friends, this semi-fictionalized version of comedian Jerry Seinfeld was named after, co-created by, based on, and played by Seinfeld himself. The series revolves around Jerry's misadventures with his best friend George Costanza, neighbor Cosmo Kramer, and ex-girlfriend Elaine Benes. He is usually the voice of reason amidst his friends' antics and the focal point of the foursome's relationship.
