Nepenthes chaniana (/nɪˈpɛnθiːz ˌtʃæniˈɑːnə/; after Datuk Chan Chew Lun, Managing Director of Natural History Publications) is a tropical pitcher plant species belonging to the genus Nepenthes.

Nepenthes chaniana belongs to the loosely defined "N. maxima complex", which also includes, among other species, N. boschiana, N. epiphytica, N. eymae, N. faizaliana, N. fusca, N. klossii, N. maxima, N. platychila, N. stenophylla, and N. vogelii.

[3] Cultivated plants of this species were for a long time misidentified as N. pilosa.

While N. pilosa is endemic to Kalimantan, N. chaniana is native to Sabah and Sarawak (Bukit Batu Lawi and other mountains).

The type specimen of N. chaniana was collected by Charles Clarke on Mount Alab, the highest peak in Crocker Range National Park.
