She was the third Navy ship named after the city of Cincinnati, Ohio, the first being Cincinnati, an ironclad commissioned in 1862, during the Civil War, and the second being Cincinnati, a protected cruiser, that was decommissioned in 1919.
Cincinnati split her pre-war career between the Atlantic and the Pacific fleets. She served in the Scouting Fleet, based in the Atlantic, in 1924 to 1927, serving in the Pacific for a brief time in 1925 for fleet maneuvers. Cincinnati joined the Asiatic Fleet in 1927, and returned to the Atlantic from 1928 to 1932. She continued to go back and forth between oceans until March 1941, when she was assigned to Neutrality Patrol in the western Atlantic.
When the United States entered World War II she was assigned to TF41, based at Recife, and used on convoy escort duties and patrols in the south Atlantic. In 1944, she sailed for the Mediterranean to support Operation Dragoon, the invasion of the south of France. After the war, she was deemed surplus and scrapped at the Philadelphia Naval Shipyard in February 1946
