Viburnum is a genus of about 150-175 species of shrubs or (in a few species) small trees in the moschatel family, Adoxaceae. Its current classification is based on molecular phylogeny. It was previously included in the family Caprifoliaceae. They are native throughout the temperate Northern Hemisphere, with a few species extending into tropical montane regions in South America and southeast Asia. In Africa, the genus is confined to the Atlas Mountains. The generic name originated in Latin, where it referred to V. lantana.
