The Dirillo, or Acate, is a {{convert|54|km|adj=on}} river in Sicily which springs from the Hyblaean Mountains and flows through the areas of Vizzini, Licodia Eubea, Mazzarrone, Chiaramonte Gulfi, Acate, Vittoria, Gela. It enters the Strait of Sicily south-east of the town of Gela. As the largest river in the area it is sometimes known as the Fiume Grande.
The river was known in antiquity as the Achates ({{langx|grc|Ἀχάτης}}). It was noted by Silius Italicus for the remarkable clearness of its waters."perlucentem splendenti gurgite Achaten", {{Cite Silius|14.228}} Theophrastus in his treatise On Stones (ca. 315 B.C.) indicates that the name of the gemstone achates (agate) was based on the source of such stones from this river.[http://www.farlang.com/gemstones/theophrastus-on-stones/page_054 Theophrastus, On Stones] Pliny the Elder makes the same connection in his Naturalis Historia[https://www.perseus.tufts.edu/cgi-bin/ptext?lookup=Plin.+Nat.+37.54 Pliny the Elder, The Natural History, Book XXXVII Chapter 54], at the Perseus Project
Agate and chalcedony can still be found here. During the period of Arab rule it became known as Wadi‑Ikrilu: ‘The River of Acrille’, an ancient Greek-Roman colony that stood in the surroundings.
In the 1950s, the Azienda Nazionale Idrogenazione Combustibili dammed the river near Licodia Eubea to create Lago Dirillo, a reservoir for the Polo petrolchimico di Gela petrochemical plants. With good fishing and camping facilities, as well its natural scenery, this area has become a tourist attraction.{{fact|date=October 2023}}
