Nepenthes longifolia (Latin: longus = long, folius = leaf) is a species of pitcher plant endemic to Sumatra. It grows at an elevation of 300 to 1200 m.
N. longifolia is closely related to N. sumatrana and is possibly a junior synonym of N. beccariana.

|---|---|---|
| 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 |
