Norval Sinclair Marley, a white Jamaican of English heritage, was the father of Robert Nesta Marley (Bob Marley).

Norval Sinclair Marley was born in 1895 and served as a captain in the British Army, and later worked as a plantation overseer in Jamaica. His background contrasted sharply with that of Cedella Booker, Bob's mother, who was a young Black Jamaican woman from rural St. Ann Parish. The racial and socio-economic disparity between them was significant, reflecting the hierarchical societal structures prevalent in Jamaica under British colonial rule. Their relationship, though brief, resulted in the birth of Bob Marley on February 6, 1945.
