Nepenthes thorelii is a tropical pitcher plant endemic to Indochina. Very little is known about N. thorelii and it is unlikely to have entered cultivation, although various other taxa are often mislabelled as this species in the plant trade. Prior to its rediscovery in 2011, N. thorelii was considered possibly extinct, both in the wild and in cultivation.
