Sir Philip Stephens, 1st Baronet (11 October 1723 – 20 November 1809) was a British politician who sat in the House of Commons for 47 years from 1759 to 1806, when he was the last surviving Member of Parliament to have served under George II. In the late 18th century, he was First Secretary of the Admiralty and later a Lord Commissioner of the British Admiralty between 1795 and 1806. He was a friend of Captain James Cook and the Pacific atoll of Caroline Island is named for his daughter. Stephens Island in British Columbia and Port Stephens in New South Wales were named for him.
