Nepenthes pantaronensis is a tropical pitcher plant native to the Philippines. It is known only from Mount Sumagaya and the Pantaron Mountain Range of central Mindanao, where it grows in lower and upper montane forest. On Mount Sumagaya it is sympatric with N. sumagaya and possible hybrids between these species have been recorded. Nepenthes pantaronensis is closely allied to N. petiolata and N. pulchra, both also from Mindanao.
