The Boloven Plateau is an elevated region in southern Laos. Most of the plateau is located within Champasak Province of Laos, though the edges of the plateau are also located in Sekong and Attapeu Provinces.
It is located between the Annamite Mountain Range, along which runs Laos’ eastern border with Vietnam, and the Mekong River to the west, at about 15°N 106°E.

The plateau's elevation ranges approximately from 1,000 to 1,350 metres (3,300 to 4,430 ft) above sea level.

The plateau is crossed by several rivers and has many scenic waterfalls. The name Boloven makes reference to the Laven ethnic group which has historically dominated the region. However, a domestic migration by the Lao ethnic group (which comprises approximately 40 to 50 percent of the population of Laos) has resulted in widespread interethnic marriage, thus modifying the ethnic composition of the region.
