The Battle of Camulodunum, also known as the Massacre of the Ninth Legion, (60 or 61 AD) was the major military victory of the Iceni and their allies over an organised Roman army during the revolt of Boudica against the Roman occupation of Britain. A large vexillation of the Legio IX Hispana were destroyed by the rebels. Attempting to relieve the besieged colonia of Camulodunum (Colchester, Essex), legionaries of the Legio IX Hispana led by Quintus Petillius Cerialis, were attacked by a horde of British tribes, led by the Iceni. Possibly 80% of the Roman foot-soldiers were killed in the battle. The event is recorded by the historian Tacitus in his Annals.

In AD 60 or 61, the southeastern area of the island rose in revolt under Boudica, while the governor, Gaius Suetonius Paulinus, was campaigning in Wales. The Iceni were joined by the Trinovantes, and their first target was Camulodunum, formerly the Trinovantian capital, now a colonia or settlement of discharged Roman soldiers. Tacitus reports it was poorly defended, and archaeology confirms its former military fortifications had been levelled by this time. The colonists appealed for aid to the procurator, Catus Decianus, who sent only two hundred auxiliaries. Camulodunum was burned, and the temple, where the last of the defenders took refuge, fell after a two-day siege. The defenders were massacred.

The Ninth Legion, commanded by Quintus Petillius Cerialis, attempted to relieve the siege. It is unlikely that the entire legionary strength of some 5,000 men was involved in the battle. Detachments of the legion were spread out across a network of small forts; on short notice, Cerialis was likely able to call on only the first cohort, possibly two others, auxiliary infantry, and a unit of some 500 cavalry - a total of perhaps 2,500 men. Cerialis set out from his base in Lindum Colonia (Lincoln). From Lindum, it was a distance of at least 110 miles. They may have taken the Roman road to Camulodunum from Durovigtum (Godmanchester, Cambridgeshire), a march of some 75 miles which would have taken three days.
