The Selby Canal is a 6-mile (9.7 km) canal with 2 locks which bypasses the lower reaches of the River Aire in Yorkshire, England, from the village of West Haddlesey to the town of Selby where it joins the River Ouse. It opened in 1778, and provided the main outlet for the Aire and Calder Navigation until 1826, when it was bypassed by a new cut from Ferrybridge to Goole.
