Santadi is a town and comune (municipality) in the Province of Sulcis Iglesiente in the autonomous island region of Sardinia in Italy, located about 35 kilometres (22 mi) southwest of Cagliari and about 20 kilometres (12 mi) southeast of Carbonia. It has 3,029 inhabitants.

Santadi borders the municipalities of Assemini, Domus de Maria, Nuxis, Piscinas, Pula, Teulada, Villa San Pietro, and Villaperuccio.

Starting from a hill next to the small town of Santadi, it is possible to see how the urban development system develops in concentric circles. This fact gave rise to the hypothesis that Santadi is what remains of the capital of the island mentioned by Plato in the third chapter of the Timaeus and in Critias.
