The Mun River (Thai: แม่น้ำมูล, RTGS: Maenam Mun, IPA: [mɛ̂ːnáːm muːn]), sometimes spelled Moon River, is a tributary of the Mekong river. It carries approximately 21,000 cubic kilometres of water per year.

It rises in the Khao Yai National Park area of the Sankamphaeng Range, near Nakhon Ratchasima in the Isan area of Thailand. It then flows east through the Khorat Plateau in southern Isan (Buriram, Surin and Sisaket provinces) for 466 miles (750 km) until it joins the Mekong at Khong Chiam in Ubon Ratchathani. The Moon River's main tributary is the Chi River, which flows into it in Kanthararom district of Sisaket province.
The Mun River used to be known as 'Moon River' by U.S. Air Force personnel stationed at Ubon Ratchathani airbase during the Vietnam War.[1]
The controversial Pak Mun dam is located near the confluence with the Mekong.
