William Dorrington (c. 1644-1718) was an English army officer. Contemporary sources often spell his surname as "Dorington", or "Dodington". A Roman Catholic in a period when Catholics often faced restrictions on military service in England, he is best known for his service in the Jacobite cause of James II. Particularly associated with the Royal Irish Regiment of Foot Guards, he rose to the rank of Major General in James's Irish Army, fighting in the Williamite War.
