The SS Richard Montgomery is a wrecked American Liberty cargo ship that was built during World War II. She was named after Richard Montgomery, an Irish officer who fought in the American Revolutionary War.

Liberty ships were a class of cargo ship built in the United States during World War II under the Emergency Shipbuilding Program. Although British in concept, the design was adopted by the United States for its simple, low-cost construction. Mass-produced on an unprecedented scale, the Liberty ship came to symbolize U.S. wartime industrial output.
