Admiral of the Fleet William Peere Williams-Freeman (6 January 1742 – 11 February 1832) (born William Peere Williams) was an officer in the Royal Navy.
He saw action aboard as a junior officer at the Battle of Quiberon Bay during the Seven Years' War.
He also took part, as captain of the fifth-rate HMS Venus, in the Battle of Rhode Island and then, as captain of the fifth-rate HMS Flora, in the second relief of Gibraltar during the American Revolutionary War.
Eventually (many years after his retirement from the Navy) Williams-Freeman became Admiral of the Fleet for a brief period before his death at the age of 90.
