Year 315 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 Philo (or, less frequently, year 439 Ab urbe condita).

• Aristodemus of Miletus, by order of Antigonus, sails to Laconia, where he receives permission from the Spartans to recruit 8000 mercenaries. He also meets Alexander (son of Polyperchon) and Polyperchon, thus establishing friendship between them and Antigonus ^[1]
