Pleasant Joseph known as Cousin Joe (December 20, 1907 — October 2, 1989) was an American blues and jazz singer, later famous for his 1940s recordings with clarinetist Sidney Bechet and saxophonist Mezz Mezzrow.

He was born in Wallace, Louisiana, United States and worked at Whitney Plantation throughout his childhood.

Until 1945 Cousin Joe toured Louisiana; that year he was asked to take part in the King Jazz recording sessions organized by Mezzrow and Bechet. Cousin Joe died in his sleep from natural causes in New Orleans, at the age of 81.
