USS Cullman (APA-78) was a Gilliam-class attack transport that served with the United States Navy from 1945 to 1946.

Embarking troops and cargo, Cullman sailed 20 July for calls at Eniwetok and Ulithi on her way to Batangas Bay, Luzon, arriving shortly after the end of hostilities on 20 August.

Sailing by way of Manila, she lifted Chinese troops from Hong Kong to Taku and Qingdao in two voyages from 24 October to 21 November.

She embarked homeward-bound servicemen at Manila for San Francisco, arriving 16 December 1945.

Cullman then returned to San Francisco where she was decommissioned on 22 May 1946 and transferred to the War Shipping Administration 30 June 1946 for disposal.
