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.

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 five years later, in 1919. As of 2023, Buenos Aires is the only Argentine city with a metro system.
