The Platani (Sicilian: Plàtani), known in ancient Greek as the Λύκος (Lykos, "wolf") or Ἁλυκός (Halykos, "Salty"), is a river in southern Sicily, Italy. It is the fifth longest in the island after Imera Meridionale, Simeto, Belice and Dittaino, with a course of 103 km, and the third for drainage basin with 1,785 km², after the Simeto and Imera Meridionale. It flows through the provinces of Palermo and Agrigento, marking the boundary between the latter and that of Caltanissetta.
The river generates at the confluence of Platani di Lercara and Platani di Castronuovo, which, respectively, springs in the comuni of Lercara Friddi (under the Pizzo Lanzone mountain) and Santo Stefano Quisquina (between the Serra della Moneta and Pizzo della Rondine mountains). From the confluence to the mouth it runs for c. 83 km; including the branch of Castronuovo the total length is 103 km. Along its course the Platani receives the waters of several affluents, including the Gallo d'Oro, Turvoli, Vallone Morella, Vallone Tumarrano and Vallone di Aragona.
