The Evarts class destroyer escorts were 73 destroyer escorts launched in the United States in 1942–1944. They served in World War II as convoy escorts and anti-submarine warfare ships.

The lead ship was USS Evarts (DE-5), launched on 7 December 1942. The first ship to be completed was commissioned on 20 January 1943 at the Boston Navy Yard; it was delivered to the Royal Navy under the Lend-Lease provisions and became HMS Bayntun . Evarts-class ships were driven by diesel-electric power with four diesel engines mounted in tandem with electric drives. The ships were prefabricated at various factories in the United States and the units brought together in the shipyards, where they were welded together on the slipways.

In all, 32 Evarts-class ships were delivered to the Royal Navy. They were classed as frigates and named after captains of the Napoleonic Wars and formed part of the Captain class along with 46 ships of the Buckley class.
