The Buenos Aires Underground, locally known as Subte, is a rapid transit system that serves the area of the city of Buenos Aires, Argentina. The first section of this network opened in 1913, making it the 13th earliest subway network in the world and the first underground railway in Latin America, the Southern Hemisphere, and the Spanish-speaking world, with the Madrid Metro opening nearly six years later, in 1919. As of 2023, Buenos Aires is the only Argentine city with a metro system.

The first phase, between Plaza Once and Caseros, which opened on 18 October 2007, currently stretches over 8.8 km between Hospitales and Facultad de Derecho stations.

Opened in 1944, the Line E was the last completely new line to be added to the Buenos Aires Underground, until 2007 when Line H was opened. The line has a history of being re-routed and extended due to having been historically the line with the lowest passenger numbers on the network.

The Buenos Aires Underground has one of the most diverse metro fleets in the world, and has had some of the oldest models in operation on any network. The network began with a relatively standardised fleet, but throughout its over 100-year-long history, it has seen numerous purchases which have created cases where some lines operate numerous models. Recently there have been increased efforts to modernise and standardise the fleets, with large purchases from China CNR Corporation and Alstom.
