USS Colusa (APA-74) was a Gilliam-class attack transport that served with the United States Navy from 1944 to 1946.

After another voyage to carry men to Midway, Colusa departed Pearl Harbor 1 September and called at Saipan, Sasebo, Okinawa, and Wakayama on duty redeploying occupation personnel.

Between 7 October, when she cleared Wakayama, and 5 January 1946, when she arrived at San Francisco, she crossed the Pacific on two Operation Magic Carpet voyages, calling at Guam, Seattle, Pearl Harbor, Nouméa, Brisbane, Hollandia, and Manus to load homeward-bound servicemen.

Colusa returned to Pearl Harbor 6 April, and there was decommissioned 16 May 1946, and transferred to the Maritime Commission 14 August 1947 for disposal.
