Thoeng (Thai: เทิง; IPA: [tʰɤ̄ːŋ]) is a district (amphoe) in the eastern part of Chiang Rai Province, northern Thailand.

Neighboring districts are (from the southwest clockwise) Pa Daet, Mueang Chiang Rai, Wiang Chai, Phaya Mengrai, Khun Tan, and Wiang Kaen of Chiang Rai Province. To the east is Bokeo Province of Laos, and to the south is Phayao Province.

Thoeng is a mountainous district. The conspicuous 1,174 m high Doi Lan rises 12 km to the east and 823 m high Doi Kham rises four km south of the town between Thoeng and Chiang Kham. There are some higher mountains in the east of the district such as 1,013 m high Doi Pha Mon and 1,442 m high Phu Chi Fa at the border with Wiang Kaen District. The Ing River, with its source in the Phi Pan Nam Range (Doi Luang in Mae Chai District, Phayao Province) flows through the plain area of Thoeng. Other rivers in the area are the Lao River, a tributary of the Kok River, from Doi Phu Lang Ka, Chiang Kham District, in the north and Ngao River from Doi Pha Mon and the Plong River.
