Doi Tung (ดอยตุง) is a mountain in the Thai highlands of Mae Fa Luang District, Chiang Rai Province, Thailand.

While not the highest elevation of the province, the 1,389 m high Doi Tung rises steeply close to the Thailand-Myanmar border.

It is the highest point of the Doi Nang Non, a subrange of the Daen Lao Range, in the area known as "Golden Triangle".

[1] The population of Doi Tung is about 11,000 people, consisting of various tribes including Akha, Lahu, Tai Lue, and Lawa.
