Anna Mae Winburn (née Darden; August 13, 1913 – September 30, 1999) was an influential American vocalist and jazz bandleader who flourished beginning in the mid-1930s. An African American, she is best known for having directed the International Sweethearts of Rhythm, an all-female big band that was perhaps one of the few – and one of the most – racially integrated dance-bands of the swing era.

Her first known publicized performance was singing with the studio band of Radio WOWO, Fort Wayne. She worked at various clubs in Indiana, including the Chateau Lido in Indianapolis (where she appeared under the pseudonym Anita Door).

From there she moved to North Omaha, Nebraska, where she sang and played guitar for a variety of territory bands, or groups whose touring activities and popularity were geographically limited to several adjoining states, that were led by Red Perkins. During that time Winburn was a collaborator of Lloyd Hunter, frequently singing for Lloyd Hunter‘s “Serenaders”. She also led the Cotton Club Boys out of Omaha, a group that at one point included the amazing guitarist Charlie Christian. When many of the musicians were lost to the World War II draft, Winburn joined the International Sweethearts of Rhythm. Soon she went to Oklahoma City and led bands for a short while. It was there that she led Eddie Durham‘s “All-Girl Orchestra”, which eventually earned her an invite to join the International Sweethearts of Rhythm.
