List of Nepenthes species

Unless otherwise noted, taxonomic determinations and all other information are sourced from Stewart McPherson's two-volume Pitcher Plants of the Old World, published in 2009.

[2] Where recent literature provides an altitudinal distribution that falls outside the range given in Pitcher Plants of the Old World, the discrepancy is noted.

In the case of archipelagos such as the Philippines, the individual islands to which the species is native are shown in brackets.

[29] Jumaat Haji Adam and C. C. Wilcock advocated the recognition of N. × kinabaluensis as a species in a 1998 article.

[113] Fossil pollen of various provenance, much of it originally described under the form taxon Droseridites, has been tentatively assigned to Nepenthes by several authors.
