John Clyde Copeland (March 27, 1937 – July 3, 1997)[1][2] was an American Texas blues guitarist and singer.

Although his early records met with little commercial success, he became a popular touring act over the next two decades.

His early recording career embraced blues, soul and rock and roll.

Copeland also played at the 1985 Montreux Jazz Festival, as a guest with Stevie Ray Vaughan and his band Double Trouble.

His later years were dogged by ill health due to a congenital heart defect.
