Sir Robert Hyde (1595–1665) was an English judge and Chief Justice of the King's Bench.
Having joined the king at Oxford, he was voted a malignant by parliament, and incapacitated from sitting in the house.
During the protectorate, he occasionally practised his profession, and his name occurs in the reports of Siderfin and Hardres.
At the Restoration he was knighted, and appointed a judge of the common pleas, 31 May 1660, and on 14 June 1660 was reinstated in the recordership of Salisbury.
Hyde's wife was Mary, daughter of Francis Baber, M.D., of Chew Magna, Somerset, but he had no children.
