Following the end of the war, "Randolph" headed home. Transiting the Panama Canal in late September, she arrived at Naval Station Norfolk on 15 October, where she was rigged for "Magic Carpet" service. Before the end of the year, she completed two trips to the Mediterranean area to return American servicemen. Then, in 1946, she became a training ship for reservists and midshipmen, and made a Mediterranean cruise in the latter half of the year. After another voyage to the Caribbean, she embarked midshipmen in the early summer of 1947 for a cruise to northern European waters. "Randolph" was placed out of commission, in reserve, 25 February 1948, and berthed at Philadelphia Naval Shipyard.
