Ernestine Jackson is an African-American actress and singer.
In 1973, Jackson originated the role of Ruth Younger in Raisin, her performance winning her the Theatre World Award and a nomination for the Tony Award for Best Performance by a Featured Actress in a Musical. Additional Broadway credits include Applause, The Bacchae, and the 1976 all-black revival of Guys and Dolls, for which she was nominated for the Tony Award for Best Performance by a Leading Actress in a Musical and the Drama Desk Award for Outstanding Featured Actress in a Musical. She also appeared in the 1966 revival of Show Boat at the New York State Theater and the 1967 revival of Finian's Rainbow at New York City Center.
Jackson portrayed Alberta Hunter in Cookin' at the Cookery: The Music and Times of Alberta Hunter, a revue that originated at the Hippodrome State Theatre in Gainesville, Florida in 1997 and then toured the country.
She portrayed Billie Holiday in the 2005 Long Wharf Theatre production of Lady Day at Emerson's Bar and Grill. In reviewing her performance, Frank Rizzo of Variety said she "nicely suggests rather than mimics the famous Holiday" and added, "Jackson handles the gliding jazz minimalism beautifully. She makes Holiday's fleeting happiness a joy and her suffering an art." Two years later she portrayed legendary entertainer Ethel Waters in Ethel Waters: His Eye is On the Sparrow.
Jackson's feature films include The Bonfire of the Vanities, Freedomland, Steam, and Forged, scheduled for release in 2010. On television she has appeared in Roots: The Next Generations, A Man Called Hawk, Law & Order, The West Wing, and Law & Order: Criminal Intent.
