Odetta Holmes, (December 31, 1930 – December 2, 2008), known as Odetta, was an American singer, actress, guitarist, songwriter, and a human rights activist, often referred to as "The Voice of the Civil Rights Movement". Her musical repertoire consisted largely of American folk music, blues, jazz, and spirituals. An important figure in the American folk music revival of the 1950s and 1960s, she was influential musically and ideologically to many of the key figures of the folk-revival of that time, including Bob Dylan, Joan Baez, Mavis Staples, and Janis Joplin.

Odetta was born in Birmingham, Alabama, grew up in Los Angeles, California, and studied music at Los Angeles City College while employed as a domestic worker. She had operatic training from the age of 13. Her mother hoped she would follow Marian Anderson, but Odetta doubted a large black girl would ever perform at the Metropolitan Opera. Her first professional experience was in musical theater in 1944, as an ensemble member for four years with the Hollywood Turnabout Puppet Theatre, working alongside Elsa Lanchester; she later joined the national touring company of the musical Finian's Rainbow in 1949.

While on tour with Finian's Rainbow, Odetta "fell in with an enthusiastic group of young balladeers in San Francisco", and after 1950 concentrated on folksinging.
