贝尔盖人，属高卢人，公元前2世纪居住在莱茵河下游，曾多次反抗罗马；公元1世纪侵入不列颠，占据从怀特岛到布里斯托尔湾的地区。

罗马帝国的比利时高卢行省及当今的比利时国家，其名称乃源自「贝尔盖」。

The Belgae (/ˈbɛldʒiː/ or /ˈbɛlɡaɪ/) were a large confederation of tribes living in northern Gaul, between the English Channel and the west bank of the Rhine, from at least the third century BC. They were discussed in depth by Julius Caesar in his account of his wars in Gaul. Some peoples in Britain were also called Belgae and O'Rahilly equated them with the Fir Bolg in Ireland. The Belgae gave their name to the Roman province of Gallia Belgica and, very much later, to the modern country of Belgium.
