Sir Robert Howard KB (1598 – 22 April 1653) was an English landowner, member of parliament, and Royalist soldier. He was involved in a scandal when his mistress Frances Coke, Viscountess Purbeck, was found guilty of adultery and was twice summoned to explain her pregnancy with his son to the Court of High Commission. During the English Civil War, Howard was in command of the defence of Bridgnorth Castle when it surrendered to the Parliamentarians in 1646.
