John Primer (born March 3, 1945, Camden, Mississippi) is an American Chicago blues and electric blues singer and guitarist.
He played guitar at Theresa's, a club in Chicago, between 1974 and 1980. He was influenced by Muddy Waters' former sideman, Sammy Lawhorn, who taught him to play slide guitar. He joined the Chicago Blues All-Stars of Willie Dixon in 1979, then the Muddy Waters's band until the latter's death in 1983. Then he joined the Teardrops of Magic Slim and began a solo career on Wolf Records.
In 1995 he released, The Real Deal, with songwriting and singing techniques showing the influence of both Dixon and Slim.
In 2013, Primer had a nomination for a Blues Music Award in the 'Traditional Blues Male Artist' category.
