The Juneau-class cruisers were United States Navy light cruisers which were modified version of the Atlanta-class cruiser design. The ships had the same dual-purpose main armament as USS Oakland (CL-95) with a much heavier secondary antiaircraft battery, while the anti-submarine depth charge tracks and torpedo tubes were removed along with a redesigned superstructure to reduce weight and increase stability. Three ships were ordered and built, all completed shortly after World War II, but only Juneau (CL-119) remained active long enough to see action during the Korean War.

The Atlanta-class cruisers increased wartime complement and armament and loss of Atlanta and Juneau revealed weaknesses in their stability and hull integrity of the ships which was addressed in a 1942 redesign at the same time as the modified Cleveland-class cruiser, the Fargo-class cruiser. The ships had the same main armament as USS Oakland (CL-95), but the bridge and superstructure were redesigned to remove weight and increase visibility, and the reduction in weight allowed increased antiaircraft guns to be added with increased stability. Watertight integrity was improved by removing doors on the lowest decks of the ship between bulkheads. In addition, all the anti-submarine armament was removed, along with the torpedo battery.

The main gun battery of the Juneau-class was composed of six dual 5 inch/38 caliber (127 mm) gun mounts (12 5-inch guns). The class was designed with a secondary anti-aircraft armament of thirty-two Bofors 40 mm anti-aircraft guns, and sixteen 20 mm rapid-fire anti-aircraft cannons with high-explosive shells. After the war, the ships were planned to convert to a 3 inch/50 caliber (76 mm) secondary armament to replace the 40mm guns, but only the Juneau was converted.
