Sandy River Valley Sign Language was a village sign language of the 19th-century Sandy River Valley in Maine. Together with the more famous Martha's Vineyard Sign Language and Henniker Sign Language, it was one of three local languages which formed the basis of American Sign Language.
The deaf communities in the valley developed in some of the 30 villages founded by settlers from Martha's Vineyard. However, it is not clear whether MVSL itself was transmitted, or if the chain was broken and a new sign language was created once a substantial deaf population was established.

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.
