Nepenthes gymnamphora /nᵻˈpɛnθiːz dʒɪmˈnæmfɔːrə/ is a tropical pitcher plant native to the Indonesian islands of Java and Sumatra. It has a wide altitudinal range of 600–2,800 metres (2,000–9,200 ft) above sea level. There is much debate surrounding the taxonomic status of this species and the taxa N. pectinata and N. xiphioides.

The specific epithet gymnamphora is derived from the Greek words gymnos (naked) and amphoreus (pitcher).

The N. gymnamphora group of related taxa has been variously interpreted as comprising a single extremely variable species (N. gymnamphora); two distinct species, one from Java (N. gymnamphora) and one from Sumatra (N. pectinata); or two species, one with a wide distribution covering Java and Sumatra (N. gymnamphora) and one with a very restricted range in Sumatra (N. xiphioides). An additional fourth undescribed taxon, known from Mount Sorik Merapi in Sumatra, may also fall within N. gymnamphora.
