Montagnard is an umbrella term for the various indigenous peoples of the Central Highlands of Vietnam. The French term Montagnard ( ) signifies a mountain dweller, and is a carryover from the French colonial period in Vietnam. In Vietnamese, they are known by the term người Thượng, although this term can also be applied to other minority ethnic groups in Vietnam. In modern Vietnam, both terms are archaic, and indigenous ethnic groups are referred to as đồng bào or người dân tộc thiểu số. Earlier they were referred to pejoratively as the mọi. Sometimes the term Degar is used for the group as well. Most of those living in the United States refer to themselves as Montagnards, while those living in Vietnam refer to themselves by their individual ethnic group.

Jarai people or Jarais are an Austronesian indigenous people and ethnic group native to Vietnam's Central Highlands, as well as in the Cambodian northeast Province of Ratanakiri. During the Vietnam War, many Jarai persons, as well as members of other Montagnard groups, collaborated with US Special Forces, and many were resettled with their families in the United States, particularly in North Carolina, after the war.
