USS Kearny (DD-432), a Gleaves-class destroyer, was a United States Navy warship during World War II.

After shakedown and sea trials, Kearny got underway 19 February 1941, from New York Harbor for St. Thomas, Virgin Islands, where she took part in the Neutrality Patrol off Fort de France, Martinique, French West Indies, until 9 March.

On October 17, 1941, while the U.S. was still officially neutral in World War II, Kearny was docked at Reykjavík in Iceland, whose occupation had been taken over from the Allies by the Americans in July that year.

Immediately on reaching the action, Kearny dropped depth charges on the U-boats, and continued to barrage throughout the night.

Regaining power in the forward engine room, Kearny steamed to Iceland at 10 knots (20 km/h), arriving 19 October.

There she screened USS Texas and Savannah on fire support missions, shot down an enemy plane, and escorted troop ships to Safi, French Morocco.

During the day of 1 January 1944, in coordination with Core's planes, Kearny fired a depth charge attack on a submarine resulting in a large oil slick.

[7] Kearny was detached from the group the beginning of June and steamed to Anzio alone to give Allied troops their last naval fire support prior to their breakthrough and capture of Rome.

She sailed from Wakayama, Japan, 29 October 1945, for home via Pearl Harbor, San Diego, and the Panama Canal, arriving Charleston, South Carolina, 5 December 1945.
