Nepenthes palawanensis is a tropical pitcher plant endemic to Sultan Peak on the island of Palawan in the Philippines, where it grows at elevations of 1,100–1,236 m (3,609–4,055 ft) above sea level.

[3] The species appears to be most closely related to N. attenboroughii, which grows on nearby Mount Victoria.

)[6] Another difference from N. attenboroughii is that the pitchers of N. palawanensis are lined with orange to red hairs.

[7][8] The discovery of N. attenboroughii, by a team that included McPherson, helped to obtain local support for the protection of the Mount Victoria range; following the discovery of N. palawanensis, it was hoped that similar support for the Sultan range might result.

[9] Nepenthes palawanensis forms natural hybrids with a taxon resembling N. philippinensis.
