Nepenthes junghuhnii (/nᵻˈpɛnθiːz jʊŋˈhuːni.aɪ/; after Friedrich Franz Wilhelm Junghuhn, who collected it between 1840 and 1842) is a tropical pitcher plant native to Sumatra. This species has been the source of much confusion since its discovery. The taxon originally named N. junghuhnii by John Muirhead Macfarlane has never been formally published (Henry Nicholas Ridley's N. junghuhnii is a heterotypic synonym of N. singalana). In 1994, taxonomist Jan Schlauer described N. junghuhnii as a "rather dubious species based on insufficient specimens".Nepenthes junghuhnii sensu Macfarlane has not been relocated in the wild since the collection of the type specimen. It is characterised by strongly leaves and appears to be most closely related to N. bongso and N. spathulata; Schlauer considers it a possible synonym of the former.
Herbarium specimens informally named N. junghuhnii by Macfarlane were collected by Junghuhn in the Batak region of North Sumatra, near Lake Toba. The specimens of N. singalana that Ridley used to describe N. junghuhnii originated from a collection by Harold Ernest Robinson and Cecil Boden Kloss on Mount Kerinci, in the Sumatran province of Jambi.
