Keres, also Keresan, is a Native American language, spoken by the Keres Pueblo people in New Mexico. Depending on the analysis, Keres is considered a small language family or a language isolate with several dialects. The varieties of each of the seven Keres pueblos are mutually intelligible with its closest neighbors. There are significant differences between the Western and Eastern groups, which are sometimes counted as separate languages.

The Indigenous languages of the Americas are the languages that were used by the Indigenous peoples of the Americas before the arrival of non-Indigenous peoples. Over a thousand of these languages are still used today, while many more are now extinct. The Indigenous languages of the Americas are not all related to each other; instead, they are classified into a hundred or so language families, as well as a number of extinct languages that are unclassified due to the lack of information on them.
