"Ma" Rainey (born Gertrude Malissa Nix Pridgett; c. April 26, 1886 – December 22, 1939) was one of the earliest known American professional blues singers and one of the first generation of such singers to record. She was billed as The Mother of the Blues.

She began performing as a young teenager (between the ages of 12 and 14), and performed under the name Ma Rainey after she and Will Rainey were married in 1904. They toured with the Rabbit Foot Minstrels and later formed their own group called Rainey and Rainey, Assassinators of the Blues. From the time of her first recording in 1923 to five years later, Ma Rainey made over 100 recordings, including "Bo-weevil Blues" (1923), "Moonshine Blues" (1923), "See See Rider" (1924), "Black Bottom" (1927), and "Soon This Morning" (1927).
