Marie Helvin (born August 13, 1952) is a former British-based American fashion model, who worked extensively with David Bailey—to whom she was married between 1975 and 1985. In the 1970s and 1980s she appeared in many fashion stories for British Vogue and posed for a series of nude photographs made by Bailey, which were published in his 1980 book Trouble and Strife. They would collaborate on four more photographic books and continued to work on multiple stories for the British, French and Italian editions of Vogue.
Helvin was born in 1952 in Tokyo, where her American G.I. father of French and Danish descent had married a local interpreter of Japanese descent. She was brought up in Hawaii from the age of four.
