HMS Phoenix was a fourth rate frigate of the English Royal Navy, built by Peter Pett II at Woolwich and launched in 1647. The term 'frigate' during the period of this ship referred to a method of construction, rather than a role which did not develop until the following century. As completed she was established with a peacetime 32 guns, but by 1652 carried 38 guns as a wartime establishment. She was enlarged during her life and by the 1660s was measured at 556 tons.
