Síkinos, a island part of the Thera province of the prefecture of Cyclades part of the South Aegean periphery of Greece. The population in 2001 was 238

Sikinos is around 42 km² large, probably a colony of Ionian Greeks. Remains of Apollo Pythios and an ancient city exists (parts of the building material have been used for the construction of churches).

Sikinos was known as Oinoe (Island of Wine) in Ancient Greece.

According to Greek Mythology Sikinos was named after the son of Thoas Sikinos. Thoas was the only man who survived the massacre in Lemnos , when all men were killed by the women of Lemnos. In a chest with the help of his daughter Hypsipyle he was thrown into the sea and arrived in Sikinos.

Sikinos was part of the Athenian empire, Macedonians, Romans, Venetian and Ottoman rulers followed. The island was attacked several time by pirates such as in 1537 by Barbarossa and in the year 1774

It contrasts with nearby islands, such as Ios, in being quiet and relatively less developed. There are two villages, one being a harbor, and the other higher up in the hills. There are a handful of tavernas in the harbor. The beach at the harbour is one of two large sandy beaches on the island. Several ancient ruins rest on the island, although some are remote. There are only 2 paved roads, although a third is being built to connect the nascent heliport and eventually a new resort on the other sandy beach, and there are aeveral well-maintained dirt roads. Much of the island is very difficult to access due to the terrain. Nearly all of the island's area is covered by terraces once used for extensive agriculture. Now only a handful are used across the island, most operating on government subsidies.
