Chom Thong District, Chiang Mai (Thai: (อำเภอ) จอมทอง, pronounced [t͡ɕɔ̄ːm tʰɔ̄ːŋ]; Northern Thai: จ๋อมตอง, pronounced [t͡ɕɔ̌m tɔ̄ːŋ]) is a district (amphoe) in the southern part of Chiang Mai province in northern Thailand.

The temple was built on the hill and named Wat Phra That Chom Thong in 1451.

The district office was originally in Ban Tha Sala, Tambon Khuang Pao.
