National Congress of American Indians (NCAI)Founded in 1944, the National Congress of American Indians (NCAI) is the oldest, largest, and most representative American Indian and Alaska Native organization serving the broad interests of tribal governments and communities. The organization’s policy issues and initiatives are driven by the consensus of our diverse membership, which consists of American Indian and Alaska Native tribal governments, tribal citizens, individuals, and Native and non-Native organizations. This site also offers a Tribal Directory that includes the links to tribal government websites, tribal organizations, Alaska Native cooperations, and other associated organizations.
