The Estación de Madrid-Chamartín Clara Campoamor or Madrid Chamartín is the second major railway station in Madrid, Spain. Located on the northern side of the city, it was built between 1970 and 1975, but more work was carried on into the early 1980s. It then superseded Atocha station, which is located just south of the city centre. However, as the AVE network expanded with a hub at Atocha, Chamartin again became Madrid's second station by passenger volume.

Madrid Atocha, also named Madrid Puerta de Atocha–Almudena Grandes, is the first major railway station in Madrid. It is the largest station serving commuter trains (Cercanías), regional trains from the south and southeast, intercity trains from Navarre, Cádiz and Huelva (Andalusia) and La Rioja, and the AVE high speed trains from Girona, Tarragona and Barcelona (Catalonia), Huesca and Zaragoza (Aragon), Sevilla, Córdoba, Málaga and Granada (Andalusia), Valencia, Castellón and Alicante. These train services are run by Spain's national rail company, Renfe. As of 2019, this station has daily services to Marseille, France.
