Year 359 (CCCLIX) was a common year starting on Friday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Eusebius and Hypatius (or, less frequently, year 1112 Ab urbe condita). The denomination 359 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.
- King Shapur II the Great of the Persian Empire invades southern Armenia. The Romans implemented a scorched earth policy and placed strong guards at the Euphrates crossings.
- Siege of Amida: Shapur II besieged the Roman fortress of Amida (modern Diyarbakir). After seventy-three days the city is conquered and the population is massacred by the Persians. Ammianus Marcellinus is a fortunate survivor and flees to Singara (Iraq).
- The first known Prefect of the city of Constantinople, Honoratus, takes office.
- Famine in Upper Rhineland. A fleet of 800 river boats built for the Rhine, crossed to the British east coast and carried back enough corn to raise the famine.
- Winter – Shapur II halts his campaign due to heavy casualties during the Persian invasion.
- July – Emperor Constantius II convenes the Council of Rimini to resolve the crisis over Arianism in the Church. Some 400 bishops of the Western Roman Empire attend, while the Eastern bishops held simultaneously a meeting at Seleucia. Given Saint Jerome's comment that, "The whole world groaned in astonishment to find itself Arian", it appears to have failed. Pope Liberius rejected the new creed at Rimini.
