Sir William Russell, 1st Baronet, of Wytley (ca. 1602 – 30 November 1669), was an English politician who sat in the House of Commons in 1625. He was an officer in the Royalist army during the English Civil War and, as Governor of Worcester, he refused entry to the Parliamentary cavalry shortly before the Battle of Powick Bridge (22 September 1642) — the first cavalry skirmish of the Civil War.
