Sir Roger Strickland (1640–1717) was an English admiral and Member of Parliament.
Strickland was the second son of Walter Strickland of Nateby Hall, Lancashire, and lived at Thornton Bridge near Aldborough in Yorkshire, a property acquired from his cousin Sir Thomas Strickland of Sizergh.
He received his first command in 1665, and the following year he commanded the 48-gun "Santa Maria" in the Four Days Battle (1–4 June 1666). In 1672 he commanded the 58-gun "Plymouth" at the Battle of Solebay, during which he recovered the "Henry", which had been captured by the Dutch. He also served in the battles of Schooneveld and Texel in 1673, as a result of which he was knighted. In 1677 he was promoted to rear-admiral and served as John Narbrough's third-in-command; on 1 April 1678, with Narbrough's successor Admiral Herbert, he captured a 40-gun Algerian cruiser.
Suspected (rightly) of being a crypto-Catholic, Strickland found his career stagnating during the later years of Charles II’s reign, and spent a period ashore in England, during which he was elected MP for Aldborough. However, he received immediate advancement on the accession of James II and returned to sea, being promoted first to vice-admiral and then to Admiral of the Blue. In the summer of 1688, he took command of the Channel Fleet, but his attempt to have the mass said publicly on board his flagship caused a mutiny, and he was shortly afterwards replaced by Lord Dartmouth. Nevertheless, he retained his rank until the Revolution, after which he resigned his commission and joined the dispossessed James II in France, later accompanying him to Ireland though apparently holding no command during the unsuccessful invasion.
