Carabus auronitens is a species of beetle in family Carabidae which was described by Johan Christian Fabricius in 1792.

This species can be distinguished from Carabus auratus, a similar species, by its longitudinal veins and its antennae: Carabus auratus has green-gold veins and its first four antenna segments are red.

It can be found under loose bark or in dead wood, and also in bogs, especially in mountains or in foreland up to 2,500 metres (8,200 ft).

The imago is mainly nocturnal and predates on smaller animals such as snails, worms or insects.

They then spend the winter under bark, in gaps in dead wood as well as in tree stubs and will be active the following year.
