Chester-le-Street is an ancient town in the northeast of England. It is in County Durham. Where it stands was a Roman fort called Concangis. This is the 'Chester' (from the Latin castra) of the town's name. 'Street' refers to the paved Roman road that ran north-south through the town. It is now called Front Street (shown at right).

Chester-le-Street is 7 miles (11 km) south of Newcastle upon Tyne and 8 miles (13 km) west of Sunderland. It is on the River Wear.
