The Dega, also known as Montagnard, are the indigenous peoples of the Central Highlands of Vietnam. The term Montagnard means "people of the mountain" in French and is a carryover from the French colonial period in Vietnam. In Vietnamese, they are known by the term người Thượng (Highlanders)—this term now can also be applied to other minority ethnic groups in Vietnam or Người dân tộc thiểu số (literally, "minority people"). Earlier they were referred to pejoratively as the mọi.
The term "Degar" is generally used only by people connected with Kok Ksor and the Degar Foundation. Most of those living in America refer to themselves as Montagnards, while those living in Vietnam refer to themselves by their individual tribe.
Below is a list of officially recognized ethnic groups in Vietnam that are indigenous to the Central Highlands and nearby areas. They speak Austroasiatic languages of the Katuic and Bahnaric, as well as Chamic languages (which belong to the Austronesian language family). Population statistics are from the 2009 Vietnam Population Census.

In 1962, the population of the Degar people in the Central Highlands was estimated to number as many as one million. Today, the population is approximately four million, of whom about one million are Degars. The 30 or so Degar tribes in the Central Highlands comprise more than six different ethnic groups who speak languages drawn primarily from the Malayo-Polynesian, Tai, and Austroasiatic language families. The main tribes, in order of population, are the Jarai, Rade, Bahnar, Koho, Mnong, and Stieng.
