Keresan Sign Language, also known as Keresan Pueblo Indian Sign Language (KPISL) or Keresign, is a village sign language spoken by many of the inhabitants of a Keresan pueblo with a relatively high incidence of congenital deafness (the pueblo is not identified in sources, but the cited population suggests it is Zia Pueblo, New Mexico).
Keresan Sign Language developed locally, and is unrelated to the trade language Plains Indian Sign Language.

^a Sign-language names reflect the region of origin. Natural sign languages are not related to the spoken language used in the same region. For example, French Sign Language originated in France, but is not related to French. Conversely, ASL and BSL both originated in English-speaking countries but are not related to each other; ASL however is related to French Sign Language.
