The Battle of Mons Graupius was, according to Tacitus, a Roman military victory in what is now Scotland, taking place in CE 83 or, less probably, 84. The exact location of the battle is a matter of debate. Historians have long questioned some details of Tacitus's account of the fight, suggesting that he exaggerated Roman success.

This was the high-water mark of Roman territory in Britain. Following this final battle, it was proclaimed that Agricola had finally subdued all the tribes of Britain. Soon afterwards he was recalled to Rome, and his post passed to Sallustius Lucullus. It is likely that Rome intended to continue the conflict, but that military requirements elsewhere in the empire necessitated a troop withdrawal and the opportunity was lost.
