USS Tills (DE-748) was a Cannon-class destroyer escort in service with the United States Navy from 1944 to 1946 and from 1950 to 1968. She was sunk as a target in 1969.

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.
