Nine species of ground beetles (Coleoptera: Carabidae) are reported for the first time from Navassa, a small island located centrally among the Greater Antilles. The uninhabited island, a U.S. National Wildlife Refuge, has rugged karst surface with forested areas of low tree diversity and open savanna or exposed rock habitats. Specimen label data, including habitat and collection notes, are given along with comments on the known distribution of each species. All species are of small size, are fully winged, and known to occur on adjacent larger islands or are widespread in the region. The small number of species is attributed to the island's size of only 5.2 km2; and its lack of sand beach, mud flat, and riparian habitats.
