Susan "Susie" Essman (born May 31, 1955) is an American stand-up comedian and comic actress in television and films. She is best known for her role as Susie Greene, the verbally abusive wife of Larry David's manager on the HBO show Curb Your Enthusiasm, and as the voice of Mittens in Bolt.

Born in Manhattan to a Jewish family, Essman grew up in the middle-class New York City suburb Mount Vernon. Her father, Leonard Essman, was an internist; he died in 2001. Her mother, Zora, taught Russian at Sarah Lawrence College. Essman received her bachelor's degree from Purchase College, part of the State University of New York (SUNY) system.

Essman is best-known for her role as Susie Greene, wife of Jeff Greene (portrayed by Jeff Garlin), on the HBO comedy series Curb Your Enthusiasm. Essman told the New York Times that by the show's third season, she could not "walk down the street anymore without people stopping her and begging her to say 'You fat fuck.'" Her doorman does not give Essman her mail until she says it to him. In the fall of 2007, Slate named Essman's character one of the best on television, and a reason the publication looked forward to the return of the show.
