Maxine Sullivan (May 13, 1911 – April 7, 1987),born Marietta Williams in Homestead, Pennsylvania, was an American jazz vocalist and performer. 　　As a vocalist, Maxine Sullivan was active for half a century, from the mid-1930s to just before her death in 1987. She is best known for her 1937 recording of a swing version of the Scottish folk song "Loch Lomond". Throughout her career, Sullivan also appeared as a performer on film as well as on stage. A precursor to better-known later vocalists such as Ella Fitzgerald, Billie Holiday, and Sarah Vaughan, Maxine Sullivan is considered one of the best jazz vocalists of the 1930s.
