The Villa María and Rufino Railway (VM&RR) (native name: Ferrocarril Villa María a Rufino) was a British-owned company that, towards the end of the 19th century, built and operated a broad gauge, 5 ft 6 in (1,676 mm), railway line in Argentina.
The line passed through the developing grain zone, which lay between the main lines operated by the BA&P and the CAR, and became a valuable feeder for the former railway. At that time the VM&R provided farmers situated along its route with their only direct access to the port and market of Buenos Aires.
Because of their common interests the VM&RR and the BA&P forged close links until finally, in 1900, the BA&P took over the VM&R.
