USS Hammann (DD-412) was a World War II-era Sims-class destroyer in the service of the United States Navy, named after Ensign Charles Hammann, a Medal of Honor recipient from World War I. Hammann was sunk during the Battle of Midway, trying to assist the sinking aircraft carrier USS Yorktown.

Hammann was launched by the Federal Shipbuilding and Drydock Company, Kearny, New Jersey on 4 February 1939; sponsored by Miss Lillian Hammann; and commissioned on 11 August 1939, Commander Arnold E. True in command. Hammann conducted shakedown off the East Coast and for the next two years participated in training and readiness operations off both coasts.

At Iceland on 7 December 1941, she quickly returned to Norfolk, Virginia, for fuel and supplies, and departed on 6 January 1942, 5 months before her destruction, for the Pacific. She arrived San Francisco on 22 January via the Panama Canal and sailed on 25 February with Vice Admiral Frank Jack Fletcher's Task Force 17 for action in the South Pacific.

The destroyer took part in training maneuvers in the New Caledonia area during early March, and on 27 March the Task Force departed for the Coral Sea. Hammann acted as screening ship and plane guard for Lexington, Returning to Tongatapu on 20 April, the Task Force sortied again into the Coral Sea on 27 April for a surprise air raid on Japanese Invasion forces on Tulagi.
