The Hinterrhein (German: [ˈhɪntɐˌʁaɪn] ⓘ; Sutsilvan: Ragn Posteriur; Sursilvan: Rein Posteriur; Rumantsch Grischun, Vallader, and Puter: Rain Posteriur; Surmiran: Ragn posteriour; Italian: Reno Posteriore), or Posterior Rhine, is the right of the two initial tributaries of the Rhine (the other being the Vorderrhein). It is located in the canton of Grisons (Graubünden), Switzerland. One of its upper tributaries is Reno di Lei, which is the outflow of Lago di Lei located in Lombardy, Italy.
Although it is shorter in length, its volume is larger than that of the Vorderrhein at their confluence near Reichenau, after which the river is called the Alpine Rhine, which flows out into Lake Constance (Bodensee).
