Massena Castings Plant (also known as the Central Foundry Division)[1] was a General Motors aluminium casting foundry located in Massena, New York.

New casting and machining techniques had to be developed to produce the light-alloy parts.

The facility was in close proximity to the Alcoa factory and was next to a border entry point between the United States and Canada.

The locations boundaries were the St. Lawrence River to the north, the St. Regis Mohawk Reservation to the east, the Raquette River to the south and property owned by Alcoa and CSX to the west.
