The Manila Metro Rail Transit System, also known as the MRT Line 3, MRT-3, or Metrostar Express, is a rapid transit system of Metro Manila, Philippines, and is composed of a single line that runs along the north and south lanes of Epifanio de los Santos Avenue (EDSA). Although it has the characteristics of light rail, such as with the type of rolling stock used, it is more akin to a rapid transit system owing to its total grade separation and high passenger throughput.

Envisioned in the 1970s as part of the Metropolitan Manila Strategic Mass Rail Transit Development Plan, the thirteen-station, 16.9-kilometer (10.5 mi) line was the second rapid transit line to be built in Metro Manila when it started full operations in 2000 under a 25-year concession agreement between its private owners and the Philippine government's Department of Transportation (DOTr).

The line is owned by the Metro Rail Transit Corporation (MRTC), a private company operating in partnership with the DOTr under a Build-Lease-Transfer agreement. Serving close to 550,000 passengers on a daily basis when MRTC's maintenance provider, Sumitomo Corp. of Japan, was handling the maintenance of the system, MRT-3 is the busiest among Metro Manila's three rapid transit lines, built with essential standards such as barrier-free access and the use of magnetic card tickets to better facilitate passenger access. Total ridership significantly exceeds its built maximum capacity of 350,000 passengers a day, with various solutions being proposed or implemented to alleviate chronic congestion in addition to the procurement of new rolling stock.

Since 2006, the system's private owners had been offering various capacity expansion proposals to the DOTC, but the DOTC never acted on these. Instead, in October 2012, the DOTC unilaterally took over the train maintenance and removed Sumitomo Corp., putting in its stead unqualified maintenance providers which led to a rapid deterioration of the MRT-3 system. In 2014, after the DOTC's handling of the line's maintenance for two years amid questions about the line's structural integrity owing to the DOTC's poor maintenance and the DOTC's pronouncements that the system in general was safe, experts from MTR HK were commissioned to review the system. MTR HK made the opinion that the rail system was compromised due to the DOTC's poor maintenance.
