  Calosoma discors is a species of ground beetle in the subfamily Carabinae, described by John Lawrence LeConte in 1857. This species is known from California and Washington, where it inhabits coastal grasslands and oak savannahs in the Sierra Nevada foothills. Adults are brachypterous, meaning they have reduced wings that limit flight capability.
