Nepenthes distillatoria (; from New Latin from Latin: destillo = to distill, -oria = adjectival ending; something from which a liquid is distilled, i.e., pitcher) is a tropical pitcher plant endemic to Sri Lanka. It was the second Nepenthes species to be described in print and the first to be formally named under the Linnaean system of taxonomy. It is therefore the type species of the genus.
