USS West Hobomac (ID-3335) was a steel–hulled cargo ship which saw service with the U.S. Navy as an auxiliary during World War I, and which later operated under the British flag during World War II before being lost to enemy action. Commissioned into the Navy just three months before the end of World War I, West Hobomac completed three voyages during the war, and made several more on the Navy's behalf in the immediate postwar period prior to decommission in 1919. Between the wars, the ship operated as the merchant vessel SS West Hobomac.
