Blind Mississippi Morris (born Morris Cummings; April 6, 1955 in Clarksdale, Mississippi, United States) is an American blues musician.
Cummings became blind at the age of four, a victim of congenital glaucoma. Morris became a solo blues performer on Beale Street, and his current backing band is called the Pocket Rockets.
Morris comes from a musical background; his cousins, Robert and Mary Diggs, led the Memphis Sheiks, while his aunt, Mary Tanner, played with the Harps of Melody. Morris is also a cousin of Willie Dixon. He was named as one of the 10 best harmonica players in the world by Bluzharp magazine.
