New Nepenthes: Volume One is a reference work by Stewart McPherson on the pitcher plants of the genus Nepenthes. It was published in 2011 by Redfern Natural History Productions and focuses on discoveries made since the release of McPherson's 2009 monograph, Pitcher Plants of the Old World. The book was edited by Alastair Robinson.

As a supplementary volume to Pitcher Plants of the Old World, the book covers taxa documented since the publication of that work in 2009, including 18 new species, 2 revised species, 1 new variety, and 2 new incompletely diagnosed taxa. The book provides detailed accounts of all of these taxa, often in the format of its predecessor, and these are accompanied by expedition reports and formal species descriptions. The content is arranged in broad geographical categories.

Seven species are formally described as new: N. appendiculata and N. epiphytica from Borneo, N. ceciliae and N. pulchra from the Philippines, N. nigra and N. undulatifolia from Sulawesi, and N. monticola from New Guinea. This last species had previously been confused with the ultrahighland N. lamii; its recognition as a distinct species necessitated the publication of a revised circumscription for N. lamii. The work also includes an emended description of N. thorelii, which was rediscovered in 2011 after more than 100 years. Two "incompletely diagnosed taxa" are also included: N. sp. Anipahan and N. sp. Luzon (later described as N. aenigma).
