The River class frigates were a class of 151 frigates launched between 1941 and 1944 for use as anti-submarine convoy escorts in the North Atlantic. The majority served with the Royal Navy and Royal Canadian Navy, with the remainder serving in the other allied navies; the Royal Australian Navy, the Free French Navy with a number transferred to the United States Navy to make up for a shortage of suitable convoy escorts until American designs became available. After World War II they found employment in other many navies the world over, and many Canadian ships were sunk as breakwaters.

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 (eg reciprocating steam engines instead of turbines) and construction techniques pioneered in the building of the Flower-class corvettes.

The River-class design was used as the basis for the United States Navys Tacoma class (know to the Royal navy as the Colony class frigate), and the hull design was later elaborated into the Loch class frigate, and subsequently the Bay class frigate
