Cape Cod Space Force Station is a United States Space Force station located in the northwest corner of Joint Base Cape Cod, United States, on Flatrock Hill in Bourne, Massachusetts. Cape Cod Space Force Station began construction in 1976 as Cape Cod Missile Early Warning Station and was renamed Cape Cod Air Force Station in 1982, before assuming its current name in 2021.

The Joint Base Cape Cod is a state-designated joint base created by the Commonwealth of Massachusetts and the United States War Department in 1935. Governor James Curley signed the state bill to allocate and purchase land for a military facility, and establishing a formal commission to manage this new state military property and personnel. After 22,000 acres of land was secured on Cape Cod, the Massachusetts National Guard began erecting tents and a basic training program in the following year. Formerly the Massachusetts Military Reservation, it was renamed in 2013 to Joint Base Cape Cod by Massachusetts; although having a name similar to many federal military installations, it has no federal recognition.
