Chrysomelina is a subtribe of leaf beetles within the Chrysomelidae, Chrysomelinae.

Larvae possess specialized glandular secretions used to repel . The subtribe exhibits diverse defensive strategies that have evolved through recruitment of oxidases from the glucose-methanol-choline (GMC) oxidoreductase superfamily.
