Nepenthes sumatrana (after Sumatra) is a species of pitcher plant endemic to Sumatra. It grows at an elevation of 0 to 800 m.

N. sumatrana is closely related to N. longifolia and N. rafflesiana.

Differences between N. longifolia and N. sumatrana (Clarke, 2001)
Character N. longifolia N. sumatrana
Tendrils on rosette leaves ≤110 cm long ≤60 cm long
Lower pitcher height usually about 1/10 the length of the tendril usually about 1/5 the length of the tendril
Lower pitchers on immature rosettes ovoid in lower parts, hip around the middle, lid ovate ovoid in lower parts, hip around the middle, lid ovate
Lower pitchers on rosettes sprouting from mature plants as for rosette pitchers on immature plants ovoid throughout, hip immediately beneath peristome, contracted at an angle of 45° to mouth, lid orbicular
Upper pitcher fragrance no fragrance sweet, fruity fragrance
Upper pitcher shape infundibular in lower ⅓, cylindrical up to hip and mouth, lid usually ovate, rarely orbicular infundibular throughout, hip immediately beneath peristome, lid orbicular
Peristome of upper pitchers never raised at front like N. rafflesiana, but often "notched" raised at front, like N. rafflesiana
