The Atlanta-class cruisers were eight United States Navy light cruisers which were designed as fast scout cruisers, flotilla leaders, or destroyer leaders, but which proved to be effective anti-aircraft cruisers during World War II. They were also known as the Atlanta-Oakland class. The Atlanta class originally had 16 x 5-inch (127 mm)/38 caliber guns in eight two-gun turrets, arranged with three superfiring turrets forward, three more superfiring aft and two waist mounts, one port and one starboard, giving the first four Atlanta-class cruisers the heaviest anti-aircraft armament of any cruiser of World War II. The last four ships of the class, starting with Oakland, had a slightly revised armament with a reduced main gun battery - the waist turrets being deleted - as they were further optimized for anti-aircraft fire in light of war experience.

The Atlanta class saw heavy action during World War II, collectively earning 54 battle stars. Two ships of the class were sunk in action: Atlanta and Juneau, both at the Naval Battle of Guadalcanal. The other six were decommissioned shortly after the war and were scrapped in the 1960s.
