The Rhade or Êđê (Rade language: Rang De) are an indigenous Austronesian ethnic group of southern Vietnam (population 398,671 in 2019).

As an ethnic group of the Vietnamese Central Highlands, the Rhade people's culture was influenced by both Champa and Cambodia.

Because of their status occupying the border region between these two influences, the term Degar is also sometimes used to refer to the peoples of the Vietnamese Central Highlands as a collective group.

According to French scholars of Southeast Asian studies, the character of Monk Kauṇḍinya symbolized the Indian cultural sphere which influenced classical Southeast Asia through Po Nagar (Champa), Neang Neak (Kampuchea), Nang Khosop (Laos), and Mae Khwan-khao (Thailand).

Like other Austronesian ethnic groups in the Central Highlands, the Rade have unique prefixes to mark people's names with the gender they were assigned at birth.

Masculine names are prefixed with Y-,[2] such as the late government official Y-Ngông Niê Kdăm.

Translators of the Rade evangelical Bible incorporated this cultural practice for most Middle Eastern and European characters (H'Mari "Mary," H'Rut "Ruth," H'Prisil "Priscilla," Y-Yôsep "Joseph," Y-Yakôp "Jacob," Y-Julius, etc.

Descent is traced through the female line, and family property is held and inherited by women.

The lineage holds corporate property such as paddy land, cattle, gongs, and jars; these are held by the senior female of the matrilineage.

Women, led by a female head of the matrilineal family, are the first ones authorised to walk on the new floor.

are told by epic tellers (Rade language: po khan) next to the fire, through the night.

Like all of the Montagnards serving in the war, translation was an important skill they offered, so they could recruit and gain the trust of more Rhade villages.

According to William Duiker, United States Foreign Officer and East-Asian professor, the training efforts, called "Civilian Irregular Defense Groups" (CIDG), were plagued with problems of arbitrary authority on the part of Vietnamese authorities and officers.
