Peter Antony Robinson (born 3 November 1962), better known as Marilyn, is an English singer known for his androgynous appearance. He was one of Britain's most successful gender bending musical artists in the 1980s. First becoming a noted figure on the London club scene, Marilyn topped the European, Japanese and Australian charts with his 1983 hit "Calling Your Name". The song was later included on his 1985 debut album Despite Straight Lines.

Marilyn also contributed to the Christmas number one Band Aid song, "Do They Know It's Christmas?" He has modelled for several fashion designers including Jean Paul Gaultier and Vivienne Westwood. Photographs of him are housed in London's National Portrait Gallery. Marilyn has been portrayed in several productions, including Boy George's stage musical Taboo which reflected on the New Romantic scene, and by the actor Freddie Fox in the 2010 BBC television film Worried About the Boy.
