Sikinos (Greek: Σίκινος) is a Greek island and municipality in the Cyclades. It is located midway between the islands of Ios and Folegandros. Sikinos is part of the Thira regional unit.
It was known as Oinoe (Island of Wine) in Ancient Greece.
It contrasts with nearby islands, such as Ios, in being quiet and relatively less developed.
There are two villages, “Allopronia” on the south sea side, being the port, and another higher up in the hills being the chora. The chora up on the hills is composed of two settlements adjacent to each other, “Castro” to the west and “Chorio” to the east. There are a handful of tavernas in the harbor. The beach at the harbor is one of two large sandy beaches on the island. Several ancient ruins rest on the island, although some are remote.
