Argentine State Railway (in Spanish: Ferrocarriles del Estado) was a State-owned railway company of Argentina, established by Law N° 6.757 in October 1909, when José Figueroa Alcorta was the President of Argentina.

The company built and operated railway lines in Argentina.

In 1925, the Argentine State Railway ranked 2nd among the most important companies in the country, operating a railway network of 6,617 km.

Most of the railway lines built by the Argentine state were metre gauge because of financial reasons.

In 1948 Argentine State Company (along with British and French companies) became part of Ferrocarriles Argentinos after nationalisation of the railway network, headed by then-President Juan Domingo Perón.
