Admiral William Hotham, 1st Baron Hotham (8 April 1736 – 2 May 1813) was a Royal Navy officer. He was the son of Sir Beaumont Hotham (died 1771), a lineal descendant of Sir John Hotham.

For this service, he was rewarded with a more powerful ship, and from 1757 onwards commanded various frigates. In 1759 his ship Melampe, with Southampton, fought a spirited action with two hostile frigates of similar force, one of which became their prize. Melampe was attached to Augustus Keppel's squadron in 1761, but was in the main employed in detached duty and made many captures. In 1776, as a Commodore, Hotham served in North American waters, and he had a great share in the Battle of St. Lucia (15 December 1778).

In November 1795, he was replaced as commander of the Mediterranean Fleet by Admiral Jervis and returned to England, and in 1797 he was made a peer of Ireland under the title of Baron Hotham of South Dalton, near Hull.
