Nepenthes reinwardtiana /nɪˈpɛnθiːz ˌraɪnwɔːrtiˈɑːnə/ is a tropical pitcher plant native to Borneo and Sumatra and to a number of smaller surrounding islands including Bangka, Natuna, Nias, and Siberut. Although some sources have included Peninsular Malaysia and Singapore within the range of this species, these records appear to be erroneous. The specific epithet reinwardtiana honours Caspar Georg Carl Reinwardt. The species has been given the vernacular name Reinwardt's pitcher-plant.
