Nepenthes kampotiana is a tropical pitcher plant native to southern Cambodia, eastern Thailand, and western Vietnam. It has an altitudinal distribution of 0–600 m above sea level. The specific epithet kampotiana refers to the Cambodian city of Kampot, close to which the first specimens of this species were collected.
This species is closely related to N. chang. Nepenthes geoffrayi is a heterotypic synonym of N. kampotiana.
In his Carnivorous Plant Database, taxonomist Jan Schlauer treats N. kampotiana as a heterotypic synonym of N. smilesii.
