Nepenthes mapuluensis (Latin: Mapulu = Mount Ilas Mapulu, -ensis = from) is a lowland Nepenthes species endemic to the Sambaliung range in east Kalimantan, Borneo. The type locality of this species is at an elevation of 800 m on Gunung Ilas Mapulu.
The description of this species by Adam & Wilcock was based on herbarium specimens that were collected by A. Kostermans in 1957, together with the type material of N. campanulata. More recently, further observations of N. mapuluensis have been made by Davis, Nerz and Wistuba and the species is now known from several peaks in the area. N. mapuluensis is restricted to limestone substrates and grows in stunted vegetation on low summit ridges.
N. mapuluensis is very similar to N. northiana and some taxonomists feel that its species status should be revised. This being the case, there seem to be several stable differences that can be used to distinguish between the two taxa; the leaves of the climbing stems of N. mapuluensis are more linear, the pitchers darker in colour and the upper pitchers narrower. It is also worth noting that N. northiana is known only from the Bau area of Sarawak, which lies several hundred kilometres away on the other side of the island.
