The Roca line is a 1,676 mm (5 ft 6 in) gauge commuter rail service in the city of Buenos Aires, Argentina, part of General Roca Railway network. The service is currently operated by State-owned company Trenes Argentinos, from the city-centre terminus of Constitución south to Alejandro Korn, Cañuelas-Ezeiza, and La Plata, and west to Sarmiento Line's station Haedo. The transfer stations between the branch lines are Avellaneda, Bosques, Berazategui and Temperley.

The line consists of 198 kilometres of track (55 of which are electrified), 70 stations, 146 grade crossings, 907 daily services through its different branches, and carries half a million passengers daily, making it the longest and most used line of the Buenos Aires commuter rail network. Currently there are large electrification and infrastructure improvement works being undertaken on the line, with brand new electric multiple units entering service on 8 June 2015.

This line had previously been run by the state-owned company Ferrocarriles Argentinos since nationalisation of the Argentine railways in 1948. Branches from Constitución to Ezeiza and Glew were electrified and the entire fleet of trains renewed, acquiring multiple units by Japanese companies Nippon Sharyo, Kinki Sharyo, Tokyu Car, and Hitachi. The electrified rail system was opened to public in November, 1985.
