Nicollette Sheridan (born 21 November 1963) is a British-born American actress. She has appeared in movies and television, and is perhaps best known for her roles as Paige Matheson on Knots Landing and as Edie Britt on Desperate Housewives.

Sheridan was born Colette Sheridan in Rustington, West Sussex, England, the daughter of British actress Sally Sheridan (née Adams). She is of Punjabi Indian descent through her maternal side. Contrary to rumour, Sheridan is not related to actress Dinah Sheridan. Sheridan's biological father has never been identified. However, Sheridan has said that she considers her mother's late ex-boyfriend, actor Telly Savalas, to be her father (and not stepfather). Sheridan's half-brother, Nick Savalas, is his son. Sheridan attended school at Millfield in Somerset and emigrated to the United States in 1973.

Sheridan made her debut in the short-lived US primetime soap opera Paper Dolls in 1984, but her breakthrough came in 1986, when she joined the cast of the CBS primetime soap Knots Landing as "Paige Matheson". She started out in a recurring role, but was a series regular by the 1988-89 season. For her performance in the role, she won the 1990 Soap Opera Digest Award for "Outstanding Lead Actress: Prime Time" and the 1991 Soap Opera Digest Award for "Outstanding Heroine: Prime Time". The same year, she was named one of People Magazine's "50 Most Beautiful People". After the series ended in 1993, she appeared in several made-for-TV movies and the films Spy Hard and Beverly Hills Ninja and auditioned for the role of Grace Adler on Will & Grace (on which she would later guest-star). Despite her carefully cultivated sex symbol image, Sheridan has only done one nude scene during her career, in the low budget 1999 film Raw Nerve, opposite Mario Van Peebles.
