An elytron (plural: elytra) is a modified, hardened forewing of certain insect orders, notably beetles (Coleoptera) and true bugs (Hemiptera).

The elytra primarily serve as protection for the hindwings underneath, which are used for flying. In some groups, the elytra are fused together, rendering the insect flightless: for example, the ground beetle's (family Carabidae).
