Johnnie Clyde Johnson (July 8, 1924 – April 13, 2005) was an American pianist who played jazz, blues and rock and roll. His work with Chuck Berry led to his induction into the Rock and Roll Hall of Fame. He was posthumously awarded the Congressional Gold Medal for breaking racial barriers in the military, as he was a Montford Point Marine – where the African-American unit endured racism and inspired social change while integrating the previously all-white Marine Corps during World War II.

Johnson was born in Fairmont, West Virginia, United States. He began playing the piano in 1928. He joined the United States Marine Corps during World War II and became a member of Bobby Troup‘s all-serviceman jazz orchestra, the Barracudas. After his service, he moved to Detroit and then Chicago, where he sat in with many notable artists, including Muddy Waters and Little Walter.
