'''''Chalcosicya''''' is a genus of leaf beetles in the subfamily Eumolpinae. It is mainly known from the West Indies, though one species is found in southern Mexico. It has recently been thought to be a sister genus to the Mediterranean ''Colaspidea'', with ''Colaspina'' as a sister genus to the former two combined.<ref name="Flowers2012">{{cite journal|last=Flowers|first=R.

The genus was first erected by the American entomologist Doris Holmes Blake in 1930 for a single new species from Cuba. In subsequent publications by Blake, she described more than 20 additional species of the genus from various islands in the West Indies. In 2012, a species of ''Chalcosicya'' was described from southern Mexico by R. Wills Flowers, expanding the range of the genus to the mainland of North America.<ref name="Flowers2012"/>

Beetles in the genus are small in size (less than 4&nbsp;mm) and have a robust, ovate body. They have a black, dark bronze, green or blue color, and are covered in scale-like hairs or setae.<ref name="Flowers2012"/>
