The River class frigates were 151 frigates launched in 1941–1944. They were designed for anti-submarine warfare and convoy protection in the Atlantic. They served in the Royal Navy, Royal Canadian Navy, Royal Australian Navy, United States Navy and Free French Navy in World War II and sold on to other navies after the war.

The Rivers were designed by naval engineer William Reed to have the endurance and anti-submarine capabilities of the Black Swan-class sloops, while being quick and cheap to build in civil dockyards using the machinery and construction techniques pioneered in the building of the Flower-class corvettes.

The River-class design was used as the basis for the Tacoma class of the United States Navy.

HMS Plym later gained fame when she was destroyed by the United Kingdom's first nuclear weapon in Operation Hurricane in 1952.
