SS Tuxpam was an oil tanker, in the service of Petroleos Mexicanos, that was sunk on 27 June 1942 by the German submarine U-129.

In 1914 it was laid up at New York City and, in December of that year, sold and renamed SS Cushing for Standard Oil of New Jersey, Bayonne.

In September 1918, it was requisitioned by the United States Navy as USS Chinampa for the Naval Overseas Transportation Service and returned to her owners in May 1919.

While sailing unescorted, on 27 June 1942, about 40 miles (64 km) southeast of Gutiérrez Zamora, Veracruz, it was attacked with two torpedoes by the German submarine U-129.

The tanker settled by the stern, after being hit by the other torpedo, but did not sink, so the U-boat surfaced and opened fire with deck guns.
