Siculiana is a town and comune in the province of Agrigento, Sicily, southern Italy, 13 km. west from the provincial capital Agrigento.

According to some historians the name derives from the distortion of the Saracen Suq al Jani (John's market), while others believe its origin stems from the Arab Suqu 'l Yuni or Supu 'l Yunani (Market of the Greeks).

The medieval hamlet of Siculiana was founded in 1310 by Frederick II Chiaramonte, who constructed a Castle, parts of which still exist today, on the ruins of the Arab fortress "Kalat Sugul", which had been destroyed in 1087 during the conquest of Sicily by Roger I of Sicily.

Siculiana’s 13 km long coast line is unspoiled and in the locality of Torre Salsa, a protected Regional Nature Reserve has been established due to its particular naturalistic and environmental interest.

Siculiana Marina is the seaside extension of Siculiana; it is a renowned summer resort on the Strait of Sicily, once an important stop in the Mediterranean. The Port of Call (Scalo) of Siculiana Marina was historically an important commercial emporium. The Caricatore (Loading Dock) was still active up to the end of 19th century.
