King of the Suessiones and commander-in-chief of the coalition of Belgic tribes against Caesar in 57 BC. Following his victory over the Belgae and the capture of Noviodunum, the main town of the Suessiones, Caesar took two of G.'s son as hostages (Caes. B Gall. 2,4,7; 2,13,1; Cass. Dio 39,1,2). ‘Galba’ appears frequently as a cognomen of the Roman gens Sulpicia, but its Celtic origin (Suet. Galba 3,1) is not certain [1. 1621ff.; 2. 349-350].
