The Eastern Commonwealth was one of the thirteen commonwealths of the pre-War United States. Created in 1969,[1] it was comprised of the former states of West Virginia, Delaware, Pennsylvania, New Jersey and New York.

Former New JerseyEdit

Great LantaEdit

Great Lanta is an area mentioned by Father Clifford, and is the post-War remains of Atlantic City. It was invaded by slavers at one point. However, one slave group led by a man named Ehren was disbanded by Ehren himself with the help of Saint Monica, and the slaves were freed.[2]

Former PennsylvaniaEdit

The PittEdit

The post-War ruins of Pittsburgh are the basis of the Fallout 3 add-on The Pitt. Ruled by slavers, it is plagued by trogs, humans who degenerated due to the hazards produced by the city's three irradiated rivers over the decades.


Philly, once reminisced by Abraham Washington, was the post-War ruins of the city of Philadelphia. He sent an expedition there to recover the Liberty Bell, to bring back and display at the Capitol Preservation Society.[3]


A town mentioned by Everett. The Pitt raiders go out on raids in the town, and is overrun by trogs. It is also a real town outside of Pittsburgh.

Former West VirginiaEdit


Appalachia is a vast swathe of post-War West Virginia. The environment and pre-War towns and structures made it through the conflict mostly intact, as the state was not directly hit by nuclear warheads, but the region was overrun by mutated creatures that wiped out practically all human survivors by 2102, when the residents of Vault 76 emerged to begin reconstruction.

Known locationsEdit


The Eastern Commonwealth appears in the Fallout 3 add-on The Pitt and Fallout 76. It is also mentioned in Fallout 3 and its add-ons Point Lookout and Mothership Zeta. It is also mentioned in the Fallout: New Vegas add-on Dead Money, Fallout 4 (as well as a cameo appearance of the Statue of Liberty in the Atomic Command game), and the Fallout Bible.
