Luther "Snake Boy" Johnson (August 30, 1934 – March 18, 1976) was an American Chicago blues and electric blues guitarist, singer and songwriter. He was also known as Luther "Snake" Johnson or Luther "Georgia Boy" Johnson, and was otherwise billed as both Luther King and Little Luther (under the latter he recorded for Chess Records in the 1960s).

Allmusic journalist, Ron Wynn, stated "Johnson's own inimitable vocals, raspy lines and tart guitar eventually create his own aura... a good, occasionally outstanding blues artist."
