The District Line is a line of the London Underground, coloured green on the Tube map. It is a "sub-surface" line, running through the central area in shallow cut-and-cover tunnels which were built by the Metropolitan District Railway and opened in stages between 1868 and 1871. The MDR was later bought by Charles Yerkes, forming part of the "Underground" group until it was nationalised in the 1930s.

The District Line has a long history. At one point it had additional branches to Uxbridge and Hounslow West but both are now operated by the Piccadilly Line. Eastbound services were run as far as the seaside town of Southend in Essex until 1939.
