USS Siboney (ID-2999) was a United States Navy troopship in World War I. She was the sister ship of USS Orizaba (ID-1536). Launched as SS Oriente, she was soon renamed after Siboney, Cuba, a landing site of United States forces during the Spanish–American War. After her navy service ended, she was SS Siboney for the New York & Cuba Mail Steamship Co.. The ship was operated under charter by American Export Lines beginning in late 1940. During World War II she served the U.S. Army as transport USAT Siboney and as hospital ship USAHS Charles A. Stafford.
