'''Ban Khor Sign Language''' ('''BKSL'''; {{Langx|th|ภาษามือบ้านค้อ}}) is a [[village sign language]] used by at least 400 people of a rice-farming community in the village of [[Ban Khor]] in a remote area of [[Isan]] (northeastern [[Thailand]]).{{sfn|Nonaka|2004}}{{sfn|Nonaka|2009}}{{sfn|Nonaka|2014}} Known locally as ''pasa kidd'' ('language of the mute'), it developed in the 1930s due to a high number of [[deaf]] people. Estimated number of users in 2009 was 16 deaf and approximately 400 hearing out of 2741 villagers.{{sfn|Nonaka|2009}} It is a [[language isolate]], independent of the other sign languages of Thailand such as [[Old Bangkok Sign Language]] and the national [[Thai Sign Language]].{{sfn|Nonaka|2014}}

Thai Sign Language is increasingly exerting an influence on BKSL. Younger Deaf attend distant residential Deaf schools where they learn Thai Sign Language. Even middle-aged hearing people are using Thai SL vocabulary mixed with BKSL. Attitudes favoring Thai SL over BKSL are beginning to be expressed.{{sfn|Nonaka|2014}}

==Other local sign languages==
{{anchor|Huay Hai Sign Language}}{{anchor|Na Sai Sign Language}}Other village sign languages have been reported from the Ban Khor area, in the villages of [[Plaa Pag]], [[Huay Hai]] and [[Na Sai]]. They have not been documented, so it is not known if they are dialects of BKSL or if they are distinct languages.{{sfn|Hurlbut|2009}}{{sfn|Nonaka|2004}}
