The Athens Metro is a rapid transit system serving the Athens urban area in Greece. Line 1 opened as a single-track conventional steam railway in 1869 and was electrified in 1904. Beginning in 1991, Elliniko Metro S.A. constructed and extended Lines 2 and 3. It has significantly changed Athens by providing a much-needed solution to the city's traffic and air pollution problem, as well as revitalising many of the areas it serves. Extensions of existing lines are under development or tender, like the Line 2 extension to Ilion where tender started in 2023, as well as a new Line 4, whose central section began construction in October 2021. The Athens Metro is actively connected with the other means of public transport, such as buses, trolleys, the Athens Tram and the Athens Suburban Railway. The Athens Metro is hailed for its modernity, and many of its stations feature works of art, exhibitions and displays of the archaeological remains found during its construction. Photography and video-taking is permitted across the whole network and street photographers often work in Athens Metro. This was the only metro system in Greece, before the Thessaloniki Metro began operations on 30th November 2024.

Rail transport in Greece has a history which began in 1869, with the completion of the then Athens & Piraeus Railway. From the 1880s to the 1920s, the majority of the network was built, reaching its heyday in 1940. From the 1950s onward, the railway system entered a period of decline, culminating in the service cuts of 2011. Ever since the 1990s, the network has been steadily modernized, but still remains smaller than its peak length. The operation of the Greek railway network is split between the Hellenic Railways Organisation (OSE), which owns and maintains the rail infrastructure; GAIAOSE, which owns the building infrastructure and the former OSE rolling stock, Hellenic Train; and other private companies that run the trains on the network. Greece is a member of the International Union of Railways (UIC). The UIC Country Code for Greece is 73.
