The Laotian langur or white-browed black langur (Trachypithecus laotum) is a species of primate in the Cercopithecidae family. It is endemic to Laos. Its natural habitat is subtropical or tropical dry forests. Genetically the Indochinese black and Hatinh langurs are very close to the Laotian Langur, and consequently it has been suggested they should be considered subspecies of it.
