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 a Montford Point Marine, where he 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. During World War II, he joined the United States Marine Corps and became a member of Bobby Troup‘s all-serviceman jazz orchestra: the Barracudas. After his service, Johnson moved to Detroit and then Chicago, where he sat in with many notable artists, including Muddy Waters and Little Walter.
