Stieng (IPA: [stiə̯ŋ], Vietnamese: Xtiêng, Khmer: ស្ទៀង) is the language of the Stieng people of southern Vietnam and adjacent areas of Cambodia, and possibly Laos (under the name Tariang). Along with Chrau and Mnong, Stieng is classified as a language of the South Bahnaric grouping of the Mon–Khmer languages within the Austroasiatic language family. In the Austroasiatic scheme, the Bahnaric languages are often cited as being most closely related to the Khmer language.
