Nepenthes mollis (; from Latin: mollis = soft; referring to the covering of hairs), or the velvet pitcher-plant, is a tropical pitcher plant species natives to Kalimantan, Borneo. It used to be known only from a single dried herbarium specimen and is the sole recognised species in the genus Nepenthes of which the pitchers are unknown. In 2019 Global Wildlife Conservation announced the rediscovery of the species.

The habitat of N. mollis is listed as dense forest on a steep slope at an elevation of 1,800 m. The species is only known from Mount Kemul, the type locality, although a wider distribution is possible, as several higher neighbouring mountains remain unexplored. Charles Clarke suggests that it may occur in mossy forest.

Nepenthes mollis has no known natural hybrids. No infraspecific taxa of this species have been described. Nepenthes mollis has no nomenclatural or taxonomic synonyms. Its conservation status is listed as Data Deficient on the 2006 IUCN Red List of Threatened Species.
