The Mahan-class destroyers served in the United States Navy before and during World War II.

The 18 ships were built by various shipyards between 1935 and 1937. The last two ships, USS Dunlap and USS Fanning were modified slightly and sometimes referred to as the Dunlap-class. The Mahans were the second and most numerous of the six classes of 1500-ton pre-war destroyers that modernized the United States Navy.

The lead ship of the class was named for Alfred T. Mahan, a Naval officer and theorist on sea power.
