Year 536 (DXXXVI) was a leap year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year after the Consulship of Belisarius (or, less frequently, year 1289 Ab urbe condita). The denomination 536 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

- October – Siege of Naples: Belisarius captures Naples after a month's siege by sending troops into the city through an abandoned Roman aqueduct.
- December 9 – Belisarius enters Rome through the Asinarian Gate; the Gothic garrison (4,000 men) flee the capital. He sends an urgent request for reinforcements to Justinian I, meanwhile preparing Rome for a siege by bringing in great quantities of food and other supplies.
- Winter – Belisarius sets up his headquarters on the Pincian Hill and repairs the neglected city walls of Rome. He stations a 5,000-man garrison, of whom half are his personal bodyguard (bucellarii). To hold parts of the city, he recruits 20,000 young Romans to man the walls.
- March – King Theodahad cedes Provence and upper Alamannia to the Franks gaining their support in the war. He sends a large Gothic army into Dalmatia. They defeat the Byzantines, Mundus is killed during the fightings at Salona, and the Byzantine army withdraws.
