Đạ Huoai is a rural district of Lâm Đồng province in the Central Highlands region of Vietnam. As of 2003 the district had a population of 34,039.[1] The district covers an area of 490 km². The district capital lies at Ma Đa Guôi.[1]
Its name Đạ Huoai (Daa-huoaai, "the stream of waiting") is related with the legend of Da Mbri, which means "river Mbri" or "hero Bri". After his death, Bri became a big river.
In addition, Mdaa-guih (now Ma Đa Guôi town) means "a place of pause", which refers to where Bri was still waiting for his lover.
