A Marilyn is a mountain or hill in the British Isles with a relative height of at least 150 metres, regardless of absolute height or other merit. The name was coined as a humorous contrast to the designation Munro, used of a Scottish mountain with a height of more than 3000 feet, which is homophonous with Monroe.

Peter Robinson (born November 3, 1962), better known as Marilyn, is a cross-dressing singer who reached fame with his song "Calling Your Name" in the 1980s.
