Samantha Karen Fox (born 15 April 1966) is an English pop singer and former glamour model from Crouch End in North London. She has appeared on a number of reality television shows—including I'm a Celebrity...Get Me Out of Here!, Celebrity Big Brother, Celebrity Wife Swap and Celebrity MasterChef—and has occasionally worked as a television presenter and actress.

After placing second in a Sunday People amateur modelling contest, Fox rose to fame as a topless Page 3 model in The Sun, where she made her first appearance in February 1983, aged 16. During her time on Page 3, she became one of the most photographed British women of the 1980s and a prominent sex symbol; she was named "Page 3 Girl of the Year" for 1984, 1985 and 1986, and insured her breasts for £1 million. She left Page 3 in 1986, aged 20, to focus on her pop music career, but made occasional glamour modeling appearances thereafter, notably featuring in Playboy magazine in 1996. In 2008, she was voted the top Page 3 model of all time.

Released in March 1986, her debut single for the Jive Records label, "Touch Me (I Want Your Body)", became a top-10 hit across Europe, North America and Australia, reaching number one in several countries. Her first three studio albums—Touch Me (1986), Samantha Fox (1987) and I Wanna Have Some Fun (1988)—all produced international hit singles; she was nominated in the British Female Solo Artist category at the Brit Awards 1988. Her subsequent albums—Just One Night (1991), 21st Century Fox (1997) and Angel with an Attitude (2005)—were less successful, but she has continued to tour and has announced a forthcoming seventh studio album, produced by Ian Masterson.

In her early career, Fox dated men including Peter Foster, the Australian fraudster, and Paul Stanley, the rhythm guitarist and lead vocalist of rock band Kiss. Following persistent rumours in the 1990s about her sexual orientation, she came out as a lesbian in 2003. She was in a long-term relationship with her former manager Myra Stratton from 2003 until Stratton's death from cancer in 2015. In 2022, she married her tour manager, Linda Birgitte Olsen.
