«Sinner Man» or «Sinnerman» is an American traditional spiritual song that has been recorded by a number of performers. The song dates to the turn of the 20th century but most modern recorded versions derive from the 1956 recording by Les Baxter,further changes and additions were codified in 1959 by the folk music group the Weavers.

«Sinnerman» (spelled as one word) is one of Nina Simone‘s most famous songs and she recorded her definitive 10-minute-plus version on her 1965 album Pastel Blues. Simone learned the lyrics of this song in her childhood when it was used at revival meetings by her mother, a Methodist minister, to help people confess their sins. In the early days of her career during the early sixties, when she was heavily involved in the Greenwich Village scene, Simone often used the long piece to end her live performances. An earlier version of the song exists, recorded live at The Village Gate, but was never used on the 1962 Colpix album Nina at the Village Gate.
