USS Carolinian (ID-1445) was a cargo ship that served in the United States Navy from 1918 to 1919. Carolinian was built as a commercial cargo ship in 1906 at West Hartlepool, England, by the Furness-Withy Company. She operated under the names SS Harley and SS Southerner. By the time the United States entered World War I in 1917, she was named SS Carolinian and was the property of the Garland Steamship Company of New York City. For most of the war, she operated under a United States Army charter. The U.S. Navy acquired her for World War I service on 5 October 1918, assigned her the naval registry Identification Number (Id. No.) 1445, and commissioned her the same day as USS Carolinian with Lieutenant Commander W. M. Fralic, USNRF, in command.
