Myanmar, Thailand, Laos, Vietnam, Cambodia, Malaysia, Indonesia, Singapore and Brunei.

72 species in the region: 30 pheasants, 27 partridges and 15 megapodes. 

Key areas include the Annamitic Range in the east, the Sundial forest that stretches from the Thai-Malay Peninsula to Sumatra and Borneo, and northern Myanmar, which lies at the eastern end of the Himalayan range. The islands of the Indonesian archipelago hold very distinct fauna.

Many Galliformes in the region are hard to detect and live in habitats that are often densely forested or difficult to travel and live in. Therefore species in this region are amongst the most poorly known of Asia's Galliformes. 

Galliformes in this region are threatened principally by habitat loss that is reaching extreme levels in some areas, such as lowland forests of Sumatra. Habitat fragmentation of once extensive tracts of forests is leaving populations of many species isolated form each other. The pressure on these species is exacerbated by hunting and in some areas larger species have become a rarity or are locally extinct.
