Pang Mapha (Thai: ปางมะผ้า, pronounced [pāːŋ mā.pʰâː]) is the northernmost district (amphoe) of Mae Hong Son province, northern Thailand.

[1] The most famous one is the Spirit Cave, discovered by Chester Gorman in the mid-1960s, was occupied from about 9000 till 5500 BCE by Hoabinhian hunters and gatherers.

During World War II Japanese troops built a road from Pai to Mueang Mae Hong Son and further to Burma.

In 1977 the government improved the road, many people from other districts and provinces, hill tribes and refugees from Myanmar moved to the area.

To improve the administration of the area, the government created the Pang Mapha minor district (king amphoe) on 1 April 1987, by splitting the two tambons Sop Pong and Pang Mapha from Mueang Mae Hong Son district.
