This is a list of Native Americans with documented tribal ancestry or affiliation in the U.S. Congress.
All entries on this list are related to Native American tribes based in the contiguous United States. No Alaska Natives have ever served in Congress. There are Native Hawaiians who have served in Congress, but they are not listed here because they are distinct from North American Natives.
Only two Native Americans served in the 115th Congress: Tom Cole (serving since 2003) and Markwayne Mullin (serving since 2013), both of whom are Republican Representatives from Oklahoma. On November 6, 2018, Democrats Sharice Davids of Kansas and Deb Haaland of New Mexico were elected to the U.S. House of Representatives, and the 116th Congress, which commenced on January 3, 2019, has four Native Americans. Davids and Haaland are the first two Native American women with documented tribal ancestry to serve in Congress. There currently are five Native Americans seated in the House, the largest delegation yet in history: Cole, Mullin, Haaland and Davids were all reelected in 2020, with Republican Yvette Herrell of New Mexico elected for the first time in 2020.

Non-voting members of the United States House of Representatives are representatives of their territory in the House of Representatives, who do not have a right to vote on proposed legislation in the full House but nevertheless have floor privileges and are able to participate in certain other House functions. Non-voting members may vote in a House committee of which they are a member and introduce legislation. There are currently six non-voting members: a delegate representing the District of Columbia, a resident commissioner representing Puerto Rico, and one delegate for each of the other four permanently inhabited US territories: American Samoa, Guam, the Northern Mariana Islands, and the US Virgin Islands. A seventh delegate, representing the Cherokee Nation, has been formally proposed but not yet seated, while an eighth, representing the Choctaw Nation, is named in a treaty but has neither been proposed nor seated. As with voting members, non-voting delegates are elected every two years, and the resident commissioner of Puerto Rico is elected every four years.
Henry Laurens Dawes was an attorney and politician, a Republican United States Senator and United States Representative from Massachusetts. He is notable for the Dawes Act (1887), which was intended to stimulate the assimilation of Native Americans by ending the tribal government and control of communal lands. Especially directed at the tribes in Indian Territory, it provided for the allotment of tribal lands to individual households of tribal members, and for their being granted United States citizenship. This also made them subject to state and federal taxes. In addition, extinguishing tribal land claims in this territory later enabled the admission of Oklahoma as a state in 1907.
