Year 293 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Cursor and Maximus (or, less frequently, year 461 Ab urbe condita). The denomination 293 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.
- The Battle of Aquilonia is fought between the Roman Republic and the Samnites, near the current city of Aquilonia in Campania (in southern Italy). The Romans, led by the consuls Lucius Papirius Cursor and Spurius Carvilius Maximus, are victorious. After the battle, the Samnites flee into the city of Aquilonia and into their camp. The camp is captured and looted by the Romans, while the city is eventually taken, with many of the Samnite survivors being slaughtered in the fighting.
- Rome suffers from the plague. The worship of Aesculapius is introduced from Epidaurus to Rome in the hope of averting the plague.
- When an invasion of nomads threatens the eastern possessions of his realm (i.e. between the Caspian Sea and the Aral Sea and the Indian Ocean), Seleucus hands over the government of these lands west of the Euphrates to his son Antiochus. Antiochus is appointed co-regent and commander-in-chief of these territories.
- The State of Qin, led by commander Bai Qi, wins a decisive victory over the States of Wei and Han in the Battle of Yique. As part of the terms of defeat, Han and Wei are forced to concede land to Qin.
