Johnny B. Moore (born Johnny Belle Moore, January 24, 1950, Clarksdale, Mississippi) is an American Chicago blues and electric blues guitarist, singer and songwriter. He was a member of Koko Taylor's backing band in the mid-1970s. He has recorded nine solo albums since 1987. Moore's music retains a link to the earlier Chicago blues of Jimmy Reed and Muddy Waters, who also travelled to Chicago from the Mississippi Delta.
"If Johnny B. Moore isn't a star in the making," stated Allmusic's Bill Dahl, "there's no justice in the world." The blues historian Gérard Herzhaft commented that "[Moore's] albums reflect a strong Delta flavor that is refreshing in the present blues scene, dominated by rock or funk overtones." However, the blues historian Tony Russell noted in 1997 that Moore "was still one of Chicago's interesting secrets".
