The Senio (Romagnol: Sēni) is a 92-kilometre (57 mi) river of Romagna in Italy, the final right-sided tributary of the river Reno. The source of the river is in the province of Florence in the Appennino Tosco-Emiliano mountains. The river flows northeast into the province of Ravenna and flows near Casola Valsenio, Riolo Terme, Castel Bolognese, Cotignola, Lugo, Bagnacavallo, Fusignano and Alfonsine before entering the Reno.^[1] The river has a tributary called the Sintria that flows into it east of Riolo Terme. The river is along the road to Imola.

The mean discharge at its mouth is about 10 cubic metres per second (350 cu ft/s); however this can vary from a minimum of 0.3 cubic metres per second (11 cu ft/s) to a maximum of 500 cubic metres per second (18,000 cu ft/s). ^{[citation needed]}
