31 BC
Year 31 BC was either a common year starting on Tuesday, Wednesday or Thursday or a leap year starting on Tuesday or Wednesday (link will display the full calendar) of the Julian calendar (the sources differ, see leap year error for further information) and a common year starting on Tuesday of the Proleptic Julian calendar. At the time, it was known as the Year of the Consulship of Antonius and Octavianus (or, less frequently, year 723 Ab urbe condita). The denomination 31 BC 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.

- Gaius Julius Caesar Octavian becomes Roman Consul for the third time. His partner is Marcus Valerius Messalla Corvinus, replacing Mark Antony
- Octavian crosses the Strait of Otranto and lands with an army (15 legions) at Panormus in Dalmatia. He marches to Toryne in the south, and establishes a bridgehead at the Gulf of Ambracia.
- Marcus Vipsanius Agrippa sails with 300 war galleys to the western Peloponnese, and occupies strategic positions around the Gulf of Corinth to cut off Antony's line of communication.
- Antony, alerted by Octavian's presence, sets up camp on the southern shore, at the promontory of Actium. He dispatches a force to isolate the camp of Octavian in the valley of Louros.
- Agrippa storms Leucas, giving Octavian an anchorage and a second depot for his land supplies. He seizes the garrison at Patrae, and takes Antony's headquarters.
- Amyntas, king of Galatia, deserts with 2,000 cavalry to Octavian. One-third of Antony's oarsmen are lost to malnutrition, disease and desertion.
- September 2 – Roman Civil War: Battle of Actium: Off the western coast of Greece, Octavian Caesar defeats naval forces under Mark Antony and Cleopatra VII.
- The Egyptian fleet (60 warships), including Cleopatra's treasure ship, retreats to Taenarus. Antony transfers his flag to a smaller vessel and breaks through Octavian's line.
