The Boite (Cadorino dialect, Guóite) is a river of the Veneto region of northern Italy. Passing through the town of Cortina d'Ampezzo, it joins the Piave at Perarolo di Cadore. The principal valley, that of the Piave, runs parallel to the mountain chain which separates the province of Belluno from the basin of the Adige. The secondary valleys, which complete the river basin, are, in descending order and on the right bank, those of Visdende, Comelico Superiore, Auronzo, Boite and Zoldo, traversed, respectively, by the Silvella, or first branch of the Piave, the Padola, Ansiei, Boite, and Mae, which all flow into the main river in a rectangular direction.
