Poros (Greek:Πόρος) is a small Greek island-pair in the southern part of the Saronic Gulf, about 58 km (36 mi) (31 nautical miles) south from Piraeus and separated from the Peloponnese by a 200 m (656 ft) wide sea channel, with the town of Galatas on the mainland across the strait. Its surface area is about 31 square kilometres (12 sq mi) and it has 3,780 inhabitants. The ancient name of Poros was Pogon. Like other ports in the Saronic, it is a popular weekend destination for Athenian travellers.
