The American Theater^[1] was a theater of operations during World War II including all continental American territory, and extending 200 miles (320 km) into the ocean.

Owing to North and South America's geographical separation from the central theaters of conflict (in Europe, the Mediterranean and Middle East, and the Pacific) the threat of an invasion of the continental U.S. or other areas in the Americas by the Axis Powers was negligible and the theater saw relatively little conflict. Military engagements include the Battle of the River Plate, submarine attacks off the East Coast, the Aleutian Islands campaign, the Battle of the St. Lawrence, and the attacks on Newfoundland. Espionage efforts included Operation Bolívar.
