Galerucella lineola is a species of leaf beetle in the family Chrysomelidae.

The basic color is brownish-yellow with a darker spot on the pronotum and on the elytra.

These beetles are considered by some a pest and can in some years do great damage to the foliage gnawing holes in the leaves.

This species is widespread in the Palearctic realm from Ireland to Japan, in the Near East, and in North Africa.

Galerucella lineola can be found along the banks of watercourses, ponds and lakes, from lowlands up to foothills.
