Native American studies (also known as American Indian, Indigenous American, Aboriginal, Native, or First Nations studies) is an interdisciplinary academic field that examines the history, culture, politics, issues, spirituality, sociology and contemporary experience of Native peoples in North America, or, taking a hemispheric approach, the Americas. Increasingly, debate has focused on the differences rather than the similarities between other Ethnic studies disciplines such as African American studies, Asian American Studies, and Latino/a Studies.

In particular, the political sovereignty of many indigenous nations marks substantive differences in historical experience from that of other racial and ethnic groups in the United States and Canada. Drawing from numerous disciplines such as anthropology, sociology, history, literature, political science, and gender studies, Native American studies scholars consider a variety of perspectives and employ diverse analytical and methodological tools in their work.

Two key concepts shape Native American studies, according to Crow Creek Lakota scholar Elizabeth Cook-Lynn, indigenousness (as defined in culture, geography, and philosophy) and sovereignty (as legally and historically defined). Practitioners advocate for decolonization of indigenous peoples, political autonomy, and the establishment of a discipline dedicated to alleviating contemporary problems facing indigenous peoples.
