Nepenthes angasanensis ( /nɨˈpɛnθiːz ˌæŋɡəsəˈnɛnsɪs/) is a tropical pitcher plant species endemic to Sumatra, where it grows at an altitude of 2200 to 2800 m above sea level. The status of this taxon is controversial as it is similar in morphology to N. mikei and N. tobaica. It has even been suggested that the taxon might represent a natural hybrid between N. densiflora and N. tobaica.
The specific epithet refers to Mount Puncak Angasan, from which the type specimen was collected. No forms or varieties of N. angasanensis have been described.
