The Atlantic Northeast is a region of North America, comprising New England in the United States and the Maritimes in Canada. Definitions of the region vary; in New England it may be restricted to the rural north, and it may also extend to all of Atlantic Canada.

The region is noted for a cultural unity, a stark climate and geography, and a shared economic history in the exploitation of logging and the regional fishery.

The Atlantica initiative is a proposal for greater economic integration of the region.
