The Grudii were a small Belgic tribe living in Gallia Belgica during the Iron Age. They were clients of the most powerful Nervii.
They are attested as Grudii by Caesar (mid-1st c. BC).
Based on Caesar's account, their territory was located somewhere in the vicinity of Nervian territory.
During the Gallic Wars (58âÂÂ50 BC), they are cited by Caesar as clients of the Nervii.
