The Cumberland Line (numbered T5, coloured magenta) is a commuter rail line operated by Sydney Trains in Sydney, New South Wales, Australia. It connects Schofields and Campbelltown stations in the western suburbs. The line opened in 1996, following the construction of a 'Y-link' track between Harris Park and Merrylands stations. The intention of this link was to allow direct services to operate from Liverpool and Campbelltown to Parramatta and Blacktown without requiring a change of trains at Granville. The line takes its name from the Cumberland Plain on which much of Western Sydney was built.

Upon its opening in 1996, the line had a regular half-hourly service in each direction consisting of 38 journeys per day. Subsequent timetables saw its services significantly reduced to the point of running only during weekday peak hours, and from 2005 to 2013 the line only ran in one direction at a time: two services ran in the morning peak from Campbelltown towards Blacktown and three services ran in the opposite direction in the evening. Some services operated to or from Quakers Hill or Schofields on the Richmond line, but the line's official terminus on network maps and other material remained at Blacktown.
