John Dunbar, Earl of Moray (died 1390) was a Scottish nobleman.
He was nephew of the previous Earl of Moray, John Randolph, 3rd Earl of Moray. However he did not inherit it the earldom automatically. On his uncle's death it reverted to the crown, and was only awarded to him a few years later around 1374.
He died at York from wounds received from the Earl of Nottingham during a tournament.
He is an important character in Courting Favour, a historical novel by Nigel Tranter.
