Carabus is a genus of beetles in the family Carabidae. The genus is highly diverse with 94 subgenera, 959 species and 2300 subspecies, thus is the largest genus in the subfamily Carabinae. The vast majority are native to the Palearctic, but 16 Nearctic species are also known. Carabus spp. are 12–50 mm (0.47–1.97 in) long, and most species are wingless and often very colourful.
