Tribal Memberships | The Affiliated Tribes of Northwest Indians

In a world of seemingly insurmountable obstacles, a special people share the belief, wisdom, and hope that in working together they may provide not only a better life for their people today, but for generations to follow. In 1953, farsighted tribal leaders in the Northwest formed the Affiliated Tribes of Northwest Indians, and dedicated it to tribal sovereignty and self-determination. Today, ATNI represents 57 Northwest tribal governments from Oregon, Washington, Idaho, Northern California, Southeast Alaska, and Western Montana. ATNI is an organization whose foundation is composed of the people it is meant to serve – the Indian peoples. Representatives from the member tribes set the policy and direction during three yearly meetings. Through consistent leadership and the legacy of inter-tribal unity and cooperation, ATNI is recognized as the strongest regional Indian organization in the United States.

In past years ATNI thrived primarily through self-generated revenues from membership dues and our annual meetings. In recent years, ATNI has sought outside funds in order to meet complicated issues head on and provide regional services to member tribes. Although the past few years have seen great gains at home, as tribes take control of their lands and develop economic partnerships, they have been faced with additional challenges from Congress. The economic gains in the past few years cannot remedy the longstanding disparity of the past hundred years. Native peoples remain on the bottom of every social indicator – high unemployment, low income, high infant mortality, high teenage suicide and substandard housing. To continue the important work of ATNI, we need your support. We invite your tribe to join as members. Your membership dues and contributions help us strengthen our current program and expand our services to all tribes and native peoples. Members become a part of the ATNI information network, receiving notices of meetings, informational mailings, and legislative alerts. For more information please contact by phone at 503.249.5770
