Nepenthes naquiyuddinii (after the Universiti Kebangsaan Malaysia Pro-Chancellor, Yang Amat Mulia Tunku Laxamana Tunku Dato' Seri Utama Naquiyuddin Ibni Tuanku Ja'afar) is a species of tropical pitcher plant. It is known only from Keningau-Kimanis Road and the foot of Mount Trus Madi, both in Sabah, Borneo. It grows at an elevation of 1400 to 1424 m in open secondary vegetation alongside Nepenthes zakriana and the closely related Nepenthes reinwardtiana. Adam and Hafiza (2006) state that the "two species exhibit many morphological differences and therefore they cannot be united into the same species".
