The Harbor Defenses of Argentia and St. John's was a United States Army Coast Artillery Corps harbor defense command in World War II. It was part of Newfoundland Base Command, established as a result of the 1940 Destroyers for Bases Agreement with the United Kingdom. It coordinated the US Army coast defenses of Naval Station Argentia and the port of St. John's, Newfoundland from January 1941 to 8 September 1945. These included coast artillery at Fort McAndrew in Argentia and Fort Pepperrell in St. John's.
