Nepenthes hamiguitanensis is a tropical pitcher plant endemic to a single peak on the Philippine island of Mindanao, where it grows at elevations of 1200–1600 m above sea level. Once thought to be a natural hybrid between N. micramphora and N. peltata, this plant is now considered a species of possible hybridogenic origin. It produces squat upper pitchers that vary greatly in pigmentation, from red speckled to yellow throughout.
The specific epithet hamiguitanensis is derived from the name of Mount Hamiguitan, to which it is endemic, and the Latin ending , meaning "from".
Although only formally described in 2010, this taxon was already known several years earlier. A herbarium specimen of N. hamiguitanensis was collected by Victor B. Amoroso and R. Aspiras on March 13, 2007, from the Mount Hamiguitan summit ridge, specifically the trail leading to San Isidro. This plant was growing in montane forest margins at an altitude of 1310 m. Designated as V.Amoroso & R.Aspiras CMUH00006494, the specimen is deposited at the Central Mindanao University Herbarium (CMUH) in Musuan, Bukidnon, Mindanao, Philippines.
Thomas Gronemeyer, Volker Heinrich and Stewart McPherson carried out field studies on N. hamiguitanensis and the other species of Mount Hamiguitan between July 22–24, 2008. The taxon was subsequently identified as a natural hybrid between N. micramphora and N. peltata in McPherson's two-volume monograph, Pitcher Plants of the Old World, published in May 2009.
