Chrysolina herbacea, also known as the Mint Leaf Beetle, or Green Mint Beetle, is a species of beetle in the family Chrysomelidae.

The species is green, with black legs and antennae. Females can range in colour from green to purplish-grey. It can be 8-9mm long and has black coloured larvae, which also feed on the mint leaves. Visually it may be confused with the much rarer Tansy beetle (Chrysolina graminis).
