Nam Yuen (Thai: น้ำยืน) is the southernmost district (Amphoe) of Ubon Ratchathani Province, northeastern Thailand.

A group of people from Det Udom moved to Ban Chanla Na Dom of Champassak during the reign of King Mongkut. Later in 1881 the king of Champassak proposed to King Chulalongkorn to upgraded Ban Chanla Na Dom to Mueang Dom Pradit, under the control of the Champassak Kingdom. When Champask became part of French Indochine, Mueang Dom Pradit was downgraded to be a tambon of Det Udom district. As the area of Det Udom was very large, the governor of Ubon Ratchathani proposed to the government to establish a minor district (King Amphoe). This was created on March 17, 1969 by splitting off the four tambon Song, Ta Kao, Yang and Dom Pradit. It was upgraded to a full district on March 29, 1974.

The name Nam Yuen has two origins: at first the district office is located in the area of the village Nam Yuen, as well as the area has three fertile rivers, Bon, Chong and Ta Em, as Nam Yuen in Thai means long-lasting water.

Neighboring districts are (from the west clockwise) Nam Khun, Det Udom, Na Chaluai of Ubon Ratchathani Province, Champasak of Laos and Preah Vihear of Cambodia.

The Dom Yai River is an important water resource.

The highest summits of the Phanom Dong Rak Range, including Phu Khi Suk (753 m), Phu Khok Yai (693 m), Phu Chep Thong (692 m), Phu Tangok (689 m) and Chong Bok (603 m) are located in this district, in the area where the borders of Thailand, Laos and Cambodia intersect.
