USS Accohanoc (YTB/YTM-545/TD-25) was a Hisada-class harbor tug in the service of the United States Navy, named after a tribe of the Powhatan confederacy.

Accohanoc was laid down on 12 April 1945, at Morris Heights, New York, by Consolidated Shipbuilding Corp.; launched on 9 July 1945; and delivered to the Navy on 28 December 1945.

[1] By that time, however, World War II had ended and the Navy's need for all types of ships had greatly diminished.

Consequently, instead of joining the Fleet, the large harbor tug was placed in reserve at Green Cove Springs, Florida, and remained inactive for 16 months.

[2] Accohanoc was used in the James River Reserve Fleet, redesignated TD-25, until she was swamped 16 September 1999, by Hurricane Floyd.
