Paralio Astros (Greek: Παράλιο Άστρος) is a traditional port serving the inland village of Astros, in Arcadia, Greece. It is part of the municipality North Kynouria and is considered a traditional settlement. This small nautical village has about one thousand inhabitants.

Paralio Astros possesses beaches and a harbour (renovated in 2015) which can accommodate small ships. A medieval Frankish fortress, most often referred to as the Astros Castle, commands the heights of a peninsula called "The Island" which juts out to form the harbour. The main square is at the foot of the castle mount.

In the village you will find lovely traditional Greek cafes and restaurants, as well as a number of small shops and boutiques able to provide with holiday essentials. In the main street of Paralio Astros you will be able to appreciate delicious meals in the shade of terraces by the sea, for lovely lazy sunny afternoons.
