Lavi (Lawi; autonym: Swoeng or səlwəŋ) is a Mon–Khmer language of the Bahnaric branch spoken in Sekong Province, Laos.
The Lavi language was discovered by Thai linguist Therapan L-Thongkum in the late 1990s.
Within the West Bahnaric branch, it is the most divergent language (Sidwell 2003).
Lavi speakers reside in the village Ban Lavi (also called Ban Fandeng), which is about 8 km south of the city of Sekong.
