This is a list of Native American politicians in the United States. These are Native Americans who served in the federal, state, or municipal governments. Native American identity is a complex and contested issue. The Bureau of Indian Affairs defines Native American as having American Indian or Alaska Native ancestry. Legally, being Native American is defined as being enrolled in a federally recognized tribe or Alaskan village. These entities establish their own membership rules, and they vary. Each must be understood independently. Ethnologically, factors such as culture, history, language, religion, and familial kinships can influence Native American identity.
