Piper, the pepper plants or pepper vines (a term used for certain Clematis in older times), are an economically and ecologically important genus in the family Piperaceae.

It contains about 1,000-2,000 species of shrubs, herbs, and lianas, many of which are dominant species in their native habitat. The diversification of this taxon is of interest to understanding the evolution of plants.
