Thessalonike of Macedon (c. 345-295 BCE) was the daughter of Philip II of Macedon (r. 359-336 BCE) and one of his several consorts, Nikesipolis of Pherae (also spelt Nicesipolis). Born to the Argead family of Macedonian rulers like her half-brother Alexander the Great (r. 336-323 BCE), Thessalonike married Cassander (r. 305-297 BCE), and after his death, she probably acted as regent for their sons.
