The Tees Valley Line is a railway route in Northern England, following part of the original Stockton and Darlington Railway route of 1825. The line covers a distance of 38 miles (61 km), and connects Darlington with Saltburn via Middlesbrough, Redcar Central and other stations across the Tees Valley.

The section of line beyond Darlington through to Bishop Auckland is branded as the Bishop Line and is supported by the Bishop Line Community Rail Partnership. The section of the route between Darlington and Saltburn is branded as the Tees Valley Line and is supported by the Tees Valley Line Rail User Group. Beyond the Bishop line's western terminus at Bishop Auckland, the tracks continue for around 16 miles (26 km) to Stanhope along what is now the Weardale Heritage Railway.
