Metrorrey, officially Sistema de Transporte Colectivo Metrorrey, is a rapid transit system that serves the metropolitan area of Monterrey. It is operated by the Sistema de Transporte Colectivo Metrorrey, which is part of the decentralized public administration of Nuevo León. In 2022, it was the sixth largest metro system in North America by ridership.

The inaugural line opened to the public on 25 April 1991 and served 17 stations. The system has since expanded. As of 2024, the system operates 50 high-floor electric trains along 3 lines, serving 40 stations with a route of 40 kilometers (25 mi).
