Guyanese Sign Language is the deaf sign language of Guyana. Little information is available. Since American Sign Language is used for education in Guyana, "Guyanese Sign Language" may simply be the local name for ASL.

^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.
