    • Alaska Corporation Boundary

    Metadata Updated: January 25, 2026

    The Alaska Native Claims Settlement Act (ANCSA) of 1971 extinguished aboriginal land title and mandated the creation of private, for-profit corporations owned by Alaska Native shareholders. Alaska Native regional corporations are owned by over 140,000 Alaska Native shareholders and hold title to nearly 27 million acres of land across Alaska. Alaska Native regional corporations manage the land for the benefit of their shareholders. ANCSA divided the state into twelve regions defined by the common heritage and shared interests of the indigenous peoples within each geographic area. The regional boundaries do not represent land owned by the Alaska Native regional corporations; instead, they established which of the twelve Alaska Native regional corporations would serve the people, villages, and communities within that area. Within each region of Alaska there is a complex landscape of governance, land ownership, roles, and relationships. While there is overlap in who the organizations represent, each entity plays a distinct role. Individuals and businesses alike experience the intricate network of Alaska Native regional corporations, Alaska Native village corporations, federally recognized tribes, city and borough governments, and Alaska Native regional non-profit organizations.
