With the end of the war on 14 August, Louisville was again seaworthy and hurriedly prepared for postwar duties.
On 16 August, she sailed for Guam to Darien, Manchuria, with Rear Admiral T. G. W. Settle on board.
From Darien, where the evacuation of Allied prisoners of war was supervised, she steamed to Tsingtao, where Japanese vessels in that area were surrendered by Vice Admiral Kaneko.
Louisville then escorted the surrendered vessels to Jinsen, Korea, after which she returned to China for further postwar duties at Chefoo.
In mid-October, she joined the Yellow Sea force for abbreviated service before proceeding, via San Pedro, to Philadelphia, where she decommissioned on 17 June 1946 and entered the Atlantic Reserve Fleet.
Remaining with that fleet for the next 13 years, Louisville was struck from the Naval Vessel Register on 1 March 1959, and sold on 14 September to the Marlene Blouse Corporation of New York.

Louisville's ship's bell is on display at the Navy Operational Support Center in Louisville, Kentucky.
One of her main battery 8-inch 55 caliber gun turrets (Turret No.
2) damaged in a kamikaze attack on January 5, 1945, was removed and replaced.
The turret was repaired, but with the end of the war it was no longer needed.
After sitting for over a decade, it was taken to the Nevada Test Site and converted into a rotating radiation detector, to collect data on nuclear tests.
The turret is located 86 miles NNW of Las Vegas (Lat 37.139455, Long -116.109085).
