Year 56 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Consulship of Lentulus and Philippus (or, less frequently, year 698 Ab urbe condita). The denomination 56 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.

By place
Britain
- This year, or possibly the following year, the king of the Trinovantes, possibly called Imanuentius, is overthrown and killed by his rival Cassivellaunus. His son Mandubracius flees to Gaul and appeals to Julius Caesar for help.
Roman Republic
- Consuls: Gnaeus Cornelius Lentulus Marcellinus and Lucius Marcius Philippus.
- Clodia accuses her former lover Marcus Caelius Rufus of trying to poison her. The trial ends with the defendant acquitted thanks to the Pro Caelio speech of Marcus Tullius Cicero. There is no further mention of the previously famous Clodia.
- Gallic War: Decimus Junius Brutus Albinus defeats the Veneti of Brittany: The Gallics lost most of their swanships to the Romans at the battle in modern-day Quiberon Bay. The strongholds on the coast are stormed and the population is slaughtered or sold into slavery.
