Nancy Sinatra (June 8, 1940 - ) is an American singer and actress. She is the daughter of the legendary singer Frank Sinatra.

She began her career as a singer and actress at the beginning of the 1960s, initially with little success. Her career peaked in the late 1960s with a string of pop music hits. Her best-known hit, "These Boots Are Made for Walkin'"--which popularized and made her synonymous with Go-Go boots--was written by Lee Hazlewood and included legendary session drummer Hal Blaine and guitarist Billy Strange on the recording - as did most of her other hits. Other well-known hits included the title song for the James Bond film, "You Only Live Twice," "Somethin' Stupid", a duet with her father, and "Some Velvet Morning", a duet with Lee Hazlewood. The latter had many cover versions, including a version by Primal Scream.

Nancy also co-starred in a number of films including Roger Corman's "The Wild Angels" with Peter Fonda and Bruce Dern, and Speedway with Elvis Presley, and starred in a number of television specials. In the 1970s she slowed down her musical activity and ceased acting in order to concentrate on being a wife and mother.

At the age of 55 she posed for Playboy in their May, 1995 issue.

Recently, a song covered by her, "Bang Bang (My Baby Shot Me Down)", was used in the Quentin Tarantino hit film Kill Bill Volume One.

More recently, she has collaborated with Morrissey, recording a version of his top-ten, 2004 hit, "Let Me Kiss You."

She has written a biography of her father entitled "Frank Sinatra, My Father".
