Retiro-Mitre, or simply Retiro, is one of the six large mainline railway station termini in Buenos Aires, Argentina. Located in the neighborhood of Retiro, it serves as terminal station for the Mitre Line that runs local trains to the northern suburbs of the Buenos Aires metropolitan area. It also functions as terminal station for the national General Mitre Railway.

The Mitre line is an Argentine broad gauge commuter rail service in Buenos Aires Province and is part of the Ferrocarril General Bartolomé Mitre division. The service is currently operated by the State-owned company Operadora Ferroviaria Sociedad del Estado after the Government of Argentina rescinded its contract with Corredores Ferroviarios in March 2015.
