Kios — A settlement in Bithynia also known as Cius
Kios or Cius was an ancient Greek city bordering the Propontis (now known as the Sea of Marmara), in Bithynia. It was colonized by the Milesians and became a place of much commercial importance.

It joined the Aetolian League, and was destroyed by Philip V of Macedon in the Second Macedonian War (200-197 BC). It was rebuilt by Prusias I of Bithynia who renamed it 'Prusias ad Mare' for himself. An important chain in the ancient Silk Road, it became known as a wealthy town.

It later became an early Christian bishopric. Following the population exchange in 1923, the Greek refugees from Cius established the village of Nea Kios, in Argolis, Greece.
