Blanche Calloway (February 9, 1904 – December 16, 1978) was a Jazz singer, bandleader, and composer from Baltimore, Maryland. She is not as well known as her younger brother Cab Calloway, but she may have been the first woman to lead an all male orchestra. Cab Calloway often credited her with being the reason he got into show business. She made her first recordings in 1925, with Louis Armstrong as a sideman on the session.
