AD 37 (XXXVII) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Proculus and Pontius (or, less frequently, year 790 Ab urbe condita). The denomination AD 37 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.

- March 18 – The Roman Senate annuls Tiberius's will, and proclaims Caligula as Roman Emperor, nullifying the joint claim of Tiberius Gemellus. Caligula's attempt to have himself deified creates friction between himself and the Senate.
- October – Caligula becomes seriously ill, or perhaps is poisoned. He recovers from his illness, but Caligula turns toward the diabolical: he starts to kill off those who are close to him, whom he sees as a serious threat.
