The North London line is a railway line of the London Overground, which passes through the inner suburbs of north London, England. Its route is a rough semicircle from the south west to the north east, avoiding central London. The line is owned and maintained by Network Rail and London Overground.

Although much of it originated as part of the North London Railway, the current route is the result of a series of amalgamations, closures and reopenings; and has a mixed third-rail and overhead electrical power supply. It is an important freight route and is used by the Richmond to Stratford service of the London Overground, as part of the National Rail network. Also between Richmond and Gunnersbury, London Underground's District line shares tracks with London Overground services, although this part is also owned and maintained by Network Rail.

The line closed in February 2010 between Gospel Oak and Stratford for the installation of a new signalling system and the extension of 30 platforms, ultimately to allow four-car trains to run on the London Overground network. The line reopened on 1 June 2010 with a reduced service and none on Sundays, and with the upgrade work completed the full seven-day service resumed on 22 May 2011.

The North London line between Richmond and North Woolwich derives from five connecting sections which were opened over 25 years from 1846:

The line between Broad Street and both Kew Bridge and Richmond was electrified by the LNWR in 1916 on the 4th rail DC system.
