The Catalauni (Gaulish: *Catu-uellaunoi 'war-chiefs') were a Belgic tribe dwelling in the modern Champagne region during the Roman period.[1] The Catalauni probably belonged to a larger tribe, either the Remi in the north or the Lingones in the south.[2] The Catuvellauni, who migrated to southern Britain in the 1st century BC, are likely part of the same tribal group.[1]
