The Cannon class was a class of destroyer escorts built by the United States primarily for antisubmarine warfare and convoy escort service during World War II. The lead ship, USS Cannon, was commissioned on 26 September 1943 at Wilmington, Delaware. Of the 116 ships ordered, 44 were cancelled and six were commissioned directly into the Free French Forces. Destroyer escorts were regular companions escorting vulnerable cargo ships.

With the decommissioning of the Philippine Navy's BRP Rajah Humabon (PS-11) in March 2018; HTMS Pin Klao (DE-413) of the Royal Thai Navy is the only ship of the class in commission.
