Chrysomela vigintipunctata, or the spotted willow leaf beetle, is a species of broad-shouldered leaf beetle belonging to the family Chrysomelidae, subfamily Chrysomelinae.

Both larvae and adults feed on the leaves of its host plants, especially Salicaceae species.

Beetles live mostly in forests, along lakes, swamps and feed on willow and Populus.
