The League of Corinth, also sometimes referred to as Hellenic League (original name: Hellenes - 'The Greeks') is a federation of Greek states created by Philip II of Macedon during the winter of 338 BC/337 BCE after the Battle of Chaeronea, to facilitate his use of military forces in his war against Persia.

The name 'League of Corinth' was coined by modern historians after the first council of the League in Corinth.

It is the first time in history that all the Greek states (with the notable exception of Sparta) manage to become part of a single political entity.
