The KamâÂÂSui languages () are a branch of the KraâÂÂDai languages spoken by the KamâÂÂSui peoples. They are spoken mainly in eastern Guizhou, western Hunan, and northern Guangxi in southern China. Small pockets of KamâÂÂSui speakers are also found in northern Vietnam and Laos.
The KamâÂÂSui branch includes about a dozen languages. Solnit (1988) considers Lakkia and Biao languages to be sister branches of KamâÂÂSui, rather than part of KamâÂÂSui itself.
The best known KamâÂÂSui languages are Dong (Kam), with over a million speakers, Mulam, Maonan, and Sui. Other KamâÂÂSui languages include Ai-Cham, Mak, and Tûen, and Chadong, which is the most recently discovered KamâÂÂSui language. Yang (2000) considers Ai-Cham and Mak to be dialects of a single language.
Graham Thurgood (1988) presents the following tentative classification for the KamâÂÂSui branch. Chadong, a language that has been described only recently by Chinese linguist Jinfang Li, is also included below. It is most closely related to Maonan. Cao Miao and Naxi Yao, which are closely related to Southern Dong, have also been added from Shi (2015).
Peter Norquest (2021:234) presents another classification for the KamâÂÂSui branch.
Nearly all speakers of KamâÂÂSui languages originate in the Qiandongnan (Dong) and Qiannan (Sui, Then, Mak, Ai-Cham) Prefectures of Guizhou, as well as the prefecture-level cities of Hechi (Mulam and Maonan) and Guilin (Chadong) in northern Guangxi. Many KamâÂÂSui speakers have also migrated to farther urban areas such as Guangzhou.
Small groups of Kam and Sui speakers also reside in Tuyên Quang Province, Vietnam, in the villages of ÃÂá»Âng Má»Âc and Há»Âng Quang, respectively.

There is a total of about 2 million KamâÂÂSui speakers.
The four largest KamâÂÂSui ethnic groups, the Dong, Shui, Mulao, and Maonan, are officially recognized by the Chinese government. Non-recognized KamâÂÂSui ethnic groups (Chadong, Then, Mak, Ai-Cham) who can still speak their own languages number less than 50,000.
The following language varieties are closely related to, or part of, Southern Dong.
The following peoples may also speak KamâÂÂSui languages.
There are also some languages in southeastern Guizhou, northern Guangxi, and southwestern Hunan that have been influenced by KamâÂÂSui languages, such as Suantang 頸汤 and Tongdao Pinghua, a Pinghua lect spoken in Tongdao Dong Autonomous County, Hunan. KamâÂÂSui languages are also in contact with Suantang 頸汤, a Sinitic language spoken by about 80,000 ethnic Miao in Baibu ç½å¸Â, Dihu å°æ¹Â, Dabaozi 大堡åÂÂ, and Sanqiao ä¸Âé¹ in Tianzhu, Huitong, and Jing counties (Chen Qiguang 2013:35). Suantang is very similar to New Xiang (æÂ°æ¹Âè¯Â), but is unintelligible with Southwestern Mandarin.
The Proto-KamâÂÂSui language is the reconstructed ancestor of the KamâÂÂSui languages.
