The Valle dei Templi (Italian: [ˈvalle dei ˈtɛmpli]; Sicilian: Vaddi di li Tempri), or Valley of the Temples, is an archaeological site in Agrigento (ancient Greek: Ακραγας, Akragas), Sicily. It is one of the most outstanding examples of ancient Greek art and architecture of Magna Graecia, and is one of the main attractions of Sicily. The term "valley" is a misnomer, the site being located on a ridge outside the town of Agrigento.

Since 1997, the entire area has been included in the UNESCO World Heritage List. The archaeological and landscape park of the Valle dei Templi, with its 1300 hectares, is the largest archaeological park in Europe and the Mediterranean basin.
