Nepenthes pilosa (Latin: pilosus = hairy) is a highland pitcher plant species belonging to the genus Nepenthes. It is characterised by a dense indumentum of long, white hairs. Pitchers are cylindrical and mostly white to yellow in colouration.

Plants in cultivation identified as N. pilosa actually represent N. chaniana, a species described by Charles Clarke in 2006. While N. pilosa is endemic to Kalimantan, N. chaniana is native to Sabah. The pitchers of N. pilosa are rounder and broader in shape than those of N. chaniana.

N. pilosa was discovered in 1899 by Indonesian botanist Amdjah, who was part of the Nieuwenhuis Expedition. The type material of this species, consisting of two specimens, was collected by Amdjah on January 28, 1899 from Bukit Batu Lesung, a mountain located near the center of Kalimantan, at an altitude of approximately 1600 m. In July 2006, Charles Clarke visited wild populations of N. pilosa on Bukit Batu Lesung to confirm its status as a distinct species. Later that year he published the description of N. chaniana.
