The Tampuan (also spelled Tompuan'”Tompoun” or “Om Poun” called in their own language or Tampuon, Tumpoun', Khmer: ទំពួន) are an indigenous ethnic group living in northeast Cambodia.

Numbering about 31,000, the Tampuan people live in the mountainous Southern and Western portions of the Cambodian province of Ratanakiri.

Today many Tampuan villages have a communal well, volleyball court, or rice mill in the center as well.

Today, many rich Tampuans build wooden houses with corrugated steel roofs, a mark of luxury.

The average married Tampuan woman bears six to eight children in her lifetime, but due to high infant mortality rates and poor medical care, fewer than six usually survive to adulthood.

Though Tampuans may raise chickens, pigs, dogs, cows, and water buffalo for food, the meat is rarely eaten apart from an animistic religious sacrifice.

[4] Tampuans also use crossbows or guns to hunt wild boars, pheasants, deer and small rodents.

They learn from a young age to play fiddles, stringed banjos, drums, flutes, and gongs.
