The Light Rail Transit system, locally known by the initialism LRT, are a series of localised automated guideway transit (AGT) systems in Singapore which acts as feeder services to the heavy rail Mass Rapid Transit (MRT), and together forms the core of the country's rail transport services. The first LRT line was opened in 1999 and the system has since expanded to two lines, each serving three new towns, namely Bukit Panjang, Sengkang and Punggol, with a total system length of approximately 30 km (19 mi). Trains on these lines have at least one station interchange link to the MRT.

The conventional definition of light rail generally refers to an upgraded form of tram that uses articulated low-floor tram cars and partial grade separation; in some cases such as the Docklands Light Railway (DLR) in London or the Skytrain in Vancouver, LRT refers to a medium-capacity rail-based light metro system. However, the term "LRT" in Singaporean parlance refers to rubber-tired automated people mover (APM) trains that are more comparable to the Metromover in Miami, the Macau Light Rapid Transit and those found in airport people mover systems, including the Changi Airport Skytrain.^[2]

Along with the MRT, the LRT is constructed and owned by the Land Transport Authority (LTA), with operating concessions currently handed to SMRT Trains Ltd, a subsidiary of SMRT Corporation, and SBS Transit Ltd, a subsidiary of ComfortDelGro. With the completion of Singapore's two LRT lines, there are currently no plans for further LRT networks in the future, aside from linking existing LRT stations to newer MRT lines.^[3][4]
