Philon, Athenian architect of the 4th century BC, is known as the planner of two important works: the portico of twelve Doric columns to the great Hall of the Mysteries at Eleusis (work commissioned by Demetrius Phalereus about 318 BC) and, under the administration of Lycurgus, an arsenal at Athens.

Philon's arsenal was destroyed by the forces of Lucius Cornelius Sulla in the Roman conquest of Athens in 86 BC.
