Ostia is a large neighbourhood in the Municipio X of the comune of Rome, Italy, near the ancient port of Rome, which is now a major archaeological site known as Ostia Antica. Ostia is also the only municipio or district of Rome on the Tyrrhenian Sea, and many Romans spend the summer holidays there. Therefore it's entirely situated within the Municipality of Rome and is the city's seaside resort.

Ostia Antica was an ancient Roman city and the port of Rome located at the mouth of the Tiber. It is near modern Ostia, 25 km (16 mi)) southwest of Rome. Due to silting and the invasion of sand, the site now lies 3 km (2 mi) from the sea. The name Ostia derives from Latin os 'mouth'.
