Office of Federal Acknowledgement

The Office of Federal Acknowledgement was established in 1978.^[2]

The two primary ways for groups who self-identify as Native American tribes or who are state-recognized tribes to become acknowledged as federally recognized tribes is either through submitting an OFA petition or through the passage of congressional legislation. The majority of the 575 federally recognized tribes did not require approval by OFA or Congress. Around two dozen tribes have been recognized through Congress, while 18 have been recognized through an OFA petition. As of 2025, 19 OFA petitions were pending.^[2]

Some tribes acknowledged by OFA include the Cowlitz Indian Tribe,^[3] the Death Valley Timbi-Sha Shoshone Band of California,^[4] the Grand Traverse Band of Ottawa and Chippewa Indians,^[5] the Jamestown S'Klallam Tribe of Washington,^[6] the Jena Band of Choctaw Indians,^[7] the Mashpee Wampanoag Tribe,^[8] the Match-e-be-nash-she-wish Band of Pottawatomi Indians of Michigan,^[9] the Mohegan Tribe^[10], the Narragansett Indian Tribe^[11], the Pamunkey Indian Tribe,^[12] the Poarch Band of Creeks,^[13] the Samish Tribe of Indians,^[14] the San Juan Southern Paiute Tribe,^[15] the Shinnecock Indian Nation,^[16] the Snoqualmie Indian Tribe,^[17] the Tunica-Biloxi Indian Tribe,^[18] and the Wampanoag Tribe of Gay Head.^[19]
