Pearl was a fifth-rate warship of the Commonwealth of England's naval forces, one of four such ships built under the 1651 Programme (the other three were Mermaid, Primrose and Nightingale).

She was built under contract at Peter Pett's shipyard at Ratcliffe, and was launched about June 1651.

The breadth was 25 feet 0 inches (7.6 metres) with a depth in hold of 10 ft 1 in (3.1 m).

After the Stuart Restoration in 1660 she was taken into the new English Royal Navy, becoming HMS Pearl.

[Note 5] She was a 28-gun vessel under the 1685 Establishment with twelve demi-culverins, ten 6-pounders, four saker cutts and two 3-pounders.
