The species occurs from southern Thailand north to Kanchanaburi Province in Central Thailand (M. Cota in litt. to M. Auliya), Peninsular (West) Malaysia and eastern Sumatra (Indonesia) (Taylor 1965, Keogh et al. 2001). The snake's range throughout this area is disjunct; however, due to extensive national and international transport of these animals within the region, and a policy in Thailand of releasing animals confiscated from wildlife traders in the closest national park, the exact native range of this species within these countries cannot be established with certainty (Zug et al. 2011). Records from elsewhere, including Viet Nam, may represent introductions or a false report of the origin of imported specimens (Zug et al. 2011). Photographs of a juvenile or subadult specimen taken in October 2011 confirm the presence of this snake in Lo Go Xa Mat National Park in southern Viet Nam, close to the Cambodian border (T.M. Phung unpubl. data), and indicate that a breeding population is likely to occur here (M. Auliya pers. comm. October 2011). If this record reflects an extension to the python's known native range, it must be hypothesized that the snake also occurs in intervening areas of southern Myanmar (M. Auliya pers. comm. October 2011). There is a record of this species from Singapore based on a single specimen recorded in 1881, leading subsequent authors to assume the species was historically native to the island (Groombridge and Luxmore 1991). This is, however, unclear, and the species is no longer found in Singapore (M. Auliya pers. comm. March 2012). This species occurs at elevations between sea level and 650 m.
