The Atlantic is a body of water off the eastern seaboard of North America.

The ocean is found to the very east of the Commonwealth and Point Lookout. It is mentioned by name on the museum kiosk in the National Archives.

 * There is an upside-down ship with several cat pictures and the word "Meow" scratched in the middle.
 * Libertalia is a raider fortress made from and in the remains of pre-War shipwrecks, much of which floats in the water north of Fort Strong and just south of Nahant Wharf.
