The National Congress of American Indians, founded in 1944, is the oldest, largest and most representative American Indian and Alaska Native organization serving the broad interests of tribal governments and communities.

NCAI has grown over the years from its modest beginnings of 100 people to include member tribes from throughout the United States. Now serving as the major national tribal government organization, NCAI is positioned to monitor federal policy and coordinated efforts to inform federal decisions that affect tribal government interests nation wide.
