USS Mexican (ID-1655) was a United States Navy cargo ship and troop transport in commission from 1917 to 1919. SS Mexican was built in 1907 at San Francisco, California, by the Union Iron Works as a commercial cargo ship for the American-Hawaiian Steamship Company of New York City. The United States Department of War acquired Mexican for World War I service on a bareboat charter basis on 10 December 1917. On 23 December 1917, the Department of War transferred Mexican to the U.S. Navy, which gave her the naval registry Identification Number (Id. No.) 1655 and commissioned her the same day as USS Mexican.
