102 BC was a year of the pre-Julian Roman calendar. It is designated as such retrospectively; contemporary documentation would have referred to the year using the Roman consular dating system.

Events

• Gaius Marius, for the fourth time, and Quintus Lutatius Catulus serve as Roman consuls.
• The Battle of Aquae Sextiae takes place. Marius decisively defeats the Teutones, a Germanic tribe that had been raiding Roman territory. This significantly reduces the Germanic threat to Italy.
• The Roman army defeats the Cimbri near what is now Vercelli, in northern Italy. Catulus shares the triumph with Marius despite Marius being generally credited with the victory.
• The Aqua Marcia aqueduct is completed in Rome.
• The Marian reforms continue to reshape the Roman army, including professionalization and standardization of equipment.
