The Mlabri or Mrabri are an ethnic group of Thailand and Laos, and have been called "the most interesting and least understood people in Southeast Asia". Only about 300 or fewer Mlabris remain in the world today, with some estimates as low as 100. A hill tribe in northern Thailand along the border with Laos, they have been groups of nomadic hunter-gatherers. The group in Thailand live close to the Hmong and northern Thai. The group living in Laos live close to other ethnic groups as well. The name Mlabri is a Thai/Lao alteration of the word Mrabri, which appears to come from a Khmuic term "people of the forest" _ in Khmu, mra means "person" and bri "forest". They are also known locally as Phi Tong Luang or "spirits of the yellow leaves", apparently because they abandon their shelters when the leaves begin to turn yellow.
