town, unitary authority of East Riding of Yorkshire, historic county of Yorkshire, England. Situated at the confluence of the Rivers Don and Ouse, it is the most westerly port of the Humber estuary and the eastern terminus of the Aire and Calder navigation system. Although Goole is in the present unitary authority of East Riding of Yorkshire, it is part of the West Riding division of the historic county. The port, located about 47 miles (75 km) from the open sea, can accommodate only small vessels, but its trade is varied because it serves a rich agricultural hinterland and the industrial areas of South and West Yorkshire. The port, shipping, and transport are major sources of employment. Other industries include food processing and the manufacture of fertilizers. Pop. (2001) 17,600.
