The Branch MRT Line was the third Mass Rapid Transit (MRT) line in Singapore, initially operated as a branch to the existing East West Line. The line was 6.5 km long with 4 stations, and was operated by the SMRT Corporation. Travelling from one end of this line to the other end took about ten minutes, and this line was coloured brown and khaki on the rail map. The line is now part of the North South Line.

The line started operations on 10 March 1990, and was merged into the North South Line when the North South Line Woodlands Extension opened on 10 February 1996. The station codes for Bukit Batok to Choa Chu Kang stations were changed to N23, N22 and N21 respectively, subsequently to their current code on the North South Line with the revamp of the system map on 31 July 2001.
