The Tille is an 83-kilometre-long (52 mi) river of eastern France (département Côte-d'Or), a right tributary of the Saône. It is formed by the confluence of three small streams near Cussey-les-Forges, on the Plateau of Langres. The Tille flows south through the following towns: Til-Châtel, Arc-sur-Tille (east of Dijon) and Genlis.
