USS Tuscaloosa (CL/CA-37) was a New Orleans-class cruiser of the U.S. Navy. Commissioned in 1934, she spent most of her career in the Atlantic and Caribbean, participating in several European wartime operations. In early 1945, she transferred to the Pacific and assisted in shore bombardment of Iwo Jima and Okinawa. She earned 7 battle stars for her service in World War II. Never damaged in battle, the ship fared better compared to her six sister ships, three of which were sunk and the other three heavily damaged.

The New Orleans-class cruisers were a class of seven heavy cruisers built for the United States Navy (USN) in the 1930s.
