The Central Entre Ríos Railway (CERR) (in Spanish: Ferrocarril Central Entrerriano) was a railway company in the Entre Ríos Province of Argentina, owned by the provincial government, which built and operated a 1,435 mm (4 ft 8 1⁄2 in) standard gauge railway network between the rivers Paraná and Uruguay. In 1892 it was sold to the British–owned Entre Ríos Railway. On 29 January 1892 the CERR was sold by the provincial government to the British-owned Entre Ríos Railway. Following nationalisation, the railway became part of the General Urquiza Railway.
