Transport in Argentina is mainly based on a complex network of routes, crossed by relatively inexpensive long-distance buses and by cargo trucks. The country also has a number of national and international airports. The importance of the long-distance train is minor today, though in the past it was widely used. Fluvial transport is mostly used for cargo.

Within the urban areas, the main transportation system is by the bus or colectivo; bus lines transport millions of people every day in the larger cities and their metropolitan areas. Buenos Aires additionally has an underground, the only one in the country, and Greater Buenos Aires is serviced by a system of suburban trains.
