The Thanon Thong Chai Range (Thai: ทิวเขาถนนธงชัย, pronounced [tʰīw kʰǎw tʰānǒn tʰōŋ t͡ɕʰāj], formerly Thanon Range; Burmese Tanen Taunggyi) is a mountain range in northern Thailand. Its tallest peak is Doi Inthanon, the highest point in Thailand. Most of the range is in Chiang Mai Province, with parts in Mae Hong Son and Lamphun Provinces.

Geologically in the Thanon Thong Chai Range, as in the other southern subranges of the Shan Hills, layers of alluvium are superimposed on hard rock. Precambrian rocks are present in this range, but absent in the ranges further east, such as the Khun Tan Range.
