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