The Mohicans ( or , alternate spelling: Mahican) are an Eastern Algonquian Native American tribe that was Algonquian-speaking. As part of the Eastern Algonquian family of tribes, they are related to the abutting Lenape, who occupied territory to the south as far as the Atlantic coast. The Mohicans occupied the upper tidal Hudson River Valley, including the confluence of the Mohawk River (where present-day Albany, New York, developed) and into western New England centered on the upper Housatonic watershed. After 1680, due to conflicts with the Mohawk during the Beaver Wars, many were driven southeastward across the present-day Massachusetts western border and the Taconic Mountains to Berkshire County around Stockbridge, Massachusetts.
