USS Slater (DE-766) is a Cannon-class destroyer escort that served in the United States Navy and later in the Hellenic (Greek) Navy. The ship was named for Frank O. Slater of Alabama, a sailor killed on the USS San Francisco (CA-38) during the Naval Battle of Guadalcanal. He was posthumously awarded the Navy Cross for gallantry in action. The USS Slater is now a museum ship on the Hudson River in Albany, New York, the only one of its kind afloat in the United States.
