USS Western Comet (ID-3569) was a United States Navy cargo ship in commission from 1918 to 1919.

Western Comet was constructed in 1918 as the commercial steel-hulled, single-screw cargo ship SS Argonne under a United States Shipping Board contract by the Northwest Steel Company at Portland, Oregon, for the French Compagnie Generale.

Shipping Board took control of Argonne and renamed her SS Western Comet, then transferred her to the U.S. Navy on 22 September 1918 for use during World War I.

The Navy assigned her the naval registry identification number 3569 and commissioned her the same day as USS Western Comet (ID-3569).

Assigned to the Naval Overseas Transportation Service, Western Comet got underway on 2 October 1918 for New York City with a cargo of flour.
