The Native American name controversy is an ongoing discussion about the changing terminology used by the Indigenous peoples of the Americas to describe themselves, as well as how they prefer to be referred to by others. Preferred terms vary primarily by region and age. As Indigenous peoples and communities are diverse, there is no consensus on naming. Historically, until late in the 20th century, most Indigenous people in the Americas were collectively called "Indians". The distinct people in the Arctic were called "Eskimos". Both terms have declined in usage in formal speech.
