Hugh Douglas, Earl of Ormonde (died 1455) was a Scottish soldier and nobleman, a member of the powerful Black Douglases.
He received from his brother the 8th Earl, the lands of Rattray, Aberdour, and Crimond in Aberdeenshire, that of Dunsyre, Lanarkshire, and those of Ardmanach (modern Redcastle, between Tore and Muir of Ord) and Ormonde (modern-day Avoch), in Invernesshire.
He led the Scots to victory at the Battle of Sark, against a scion of the old Douglas enemy, Henry Percy, 2nd Earl of Northumberland.
Ormonde was left in control of the vast Douglas estates when his brother went on pilgrimage to Rome in 1450.
Moray died of his wounds, Balvenie escaped; Ormonde, however, was captured, tried and executed, his estates forfeit.
