J.B. LenoirJ.B. Lenoir (March 5, 1929 – April 29, 1967) was an American blues guitarist, singer and songwriter born in Monticello, Mississippi.
The Civil Rights and Free Speech movements in the U.S. in the 1960s prompted J. B. to record several LPs using acoustic guitar, sometimes accompanied by Willie Dixon on the acoustic bass or drums. His work at this time had an unusually direct political content relative to racism or Vietnam War issues.

Nel 2003 Wim Wenders - nell'ambito del progetto "The Blues" ideato da Martin Scorsese - ha dedicato un film, "The Soul of a Man", a Lenoir e ad altre due icone del blues, Blind Willie Johnson e Skip James. Sempre nel 2003 la Chess ha proposto una nuova compilation di brani di Lenoir, presentata da Scorsese.
