Tyne, River, lies in northeastern England. It begins where the North Tyne and the South Tyne merge, west of Hexham in Northumberland. From there, it flows 30 miles (48 kilometers) eastward into the North Sea. The River Tyne can accommodate oceangoing ships as far as Newcastle upon Tyne. Both banks of the river, from Newcastle to the sea, are lined with docks and industrial works. This industrial center is known as Tyneside.
