Iliou Melathron (griechisch Ιλίου Μέλαθρον, Palast von Ilion) ist ein Neorenaissance-Palais im Zentrum der griechischen Hauptstadt Athen, das sich Heinrich Schliemann von seinem Freund, dem Architekten Ernst Ziller, als Familienwohnsitz erbauen ließ. Heute beherbergt es das Numismatische Museum.

The Iliou Melathron is located in downtown Athens and home of the Numismatic Museum Athens.
It was built in 1878-1879 and designed by the German architect Ernst Ziller, as the residence of the Schliemann family.
Its name, meaning the Palace of Troy, was associated with the discovery of the ancient city by Heinrich Schliemann.
