USS Irene Forsyte (IX-93) was a three masted schooner originally built as MacLean Clan which was briefly converted to a Q-ship, of the United States Navy.

Given a new lease on life by the increased shipping traffic provoked by the war, she served in the coal trade between New England and Nova Scotia into 1942.

At this time, the U.S. Navy began looking for a smaller coastal vessel to serve as a Q-ship, complementing the larger decoy ships Big Horn, Asterion, and Atik.

Based on the experience of Q-ships during World War I, it was hoped Irene Forsyte, with her relatively heavy armament concealed, could lure German submarines into close quarters on the surface and sink them with gunfire.

In commenting on the report of the Naval Inspector General, Commander in Chief, United States Fleet (Cominch) wrote: The schooner arrived New York 8 November 1943 and, after an inspection three days later, she was decommissioned 16 December.

Stricken from the Naval Vessel Register on 22 December 1944, the schooner was transferred to the Maritime Commission and eventually sold at public auction 18 October 1945.

The aging schooner met her end off La Ceiba when, heavily laden, she ran into bad weather, took on water and sank on 21 December 1951.
