Nepenthes cornuta is a tropical pitcher plant native to the Philippines. It is known only from the Pantaron Mountain Range of central Mindanao, where it grows terrestrially on ultramafic soils at around 1000 m above sea level.[1]

This species is most closely allied to N. ceciliae and N. copelandii, both also from Mindanao. All three belong to the much larger "N. alata group",[1] which also includes N. alata, N. extincta, N. graciliflora, N. hamiguitanensis, N. kitanglad, N. kurata, N. leyte, N. mindanaoensis, N. negros, N. ramos, N. saranganiensis, and N. ultra.[2][3][4][5] These species are united by a number of morphological characters, including winged petioles, lids with basal ridges on the lower surface (often elaborated into appendages), and upper pitchers that are usually broadest near the base.[2][3]

The specific epithet cornuta is Latin for "horned" and refers to the shape of the upper pitchers.[1]

The discovery and recognition of this taxon as a new species was announced online in September 2012, under the placeholder name "Nepenthes species 1".[6]
