USS Colhoun was a Wickes-class destroyer of the United States Navy, built at Fore River in Quincy. She was launched on 21 February 1918 and commissioned on 13 June 1918 as DD-85.
The destroyer hull was converted into a high-speed transport and redesignated APD-2. A later ship named Colhoun, DD-801, is a different hull.
On 7 August 1942 she took part in the landings on Guadalcanal and Tulagi. Serving as a high-speed transport, she put Marines ashore at Tulagi.
Little, McKean, and Gregory were with her when the Marines went ashore at Tulagi. George Bernard Madden was in command of Colhoun that day. Aircraft sank her off Kukum on 30 August 1942. The loss is not credited to one plane.
She went down as the high-speed transport APD-2, the hull that had entered service in 1918 as the destroyer DD-85. The Tulagi landing and the sinking off Kukum both came in August 1942.
