Isaac Townsend (c. 1685 – 21 November 1765) was an admiral in the British Royal Navy and a Member of Parliament.

He entered Parliament in 1744 as member for the naval port of Portsmouth, and represented that town until 1754.

He became governor of Greenwich Hospital in 1754, and in this capacity in 1757 he had custody of Admiral Byng, who was under arrest there before his court-martial.

He is frequently confused with his uncle, a naval officer also named Isaac Townsend (d.1731) who is commemorated by a substantial memorial in the north transept of Winchester Cathedral.
