This article is a list of different language classification proposals developed for indigenous languages of the Americas. The article is divided into North, Central, and South America sections; however, the classifications do not always neatly correspond to these continent divisions.
(See: Indigenous languages of the Americas for the main article about these languages.)
An early attempt at North American language classification was attempted by A. A. Albert Gallatin published in 1826, 1836, and 1848. Gallatin's classifications are missing several languages which are later recorded in the classifications by Daniel G. Brinton and John Wesley Powell. (Gallatin supported the assimilation of indigenous peoples to Euro-American culture.)

John Wesley Powell, an explorer who served as director of the Bureau of American Ethnology, published a classification of 58 "stocks" that is the "cornerstone" of genetic classifications in North America. Powell's classification was influenced by Gallatin to a large extent.
