Main Cast Members and Characters
Jerry Seinfeld
Jerry Seinfeld stars as a fictionalized version of himself, a comedian navigating everyday life in New York City.

His work off camera and on informs a large portion of the series’ ensemble dynamic.
Julia Louis-Dreyfus
Julia Louis-Dreyfus portrayed Elaine Benes, Jerry’s ex-girlfriend and a sharp-witted presence. Her chemistry with the rest of the cast helped define the show’s balance of sarcasm and sincerity. She appears consistently and is credited among the principal cast for the majority of the series.
Michael Richards

Other On-Screen Contributors

The producing staff coordinated writing, casting, and scheduling to support a consistent release pace.

The writers’ room was central to the series’ long-term planning, with episodes often built from detailed outlines and repeated drafts.
