Line 3 of the Athens Metro runs from Agia Marina to Airport, via Syntagma, although some trains reverse at Doukissis Plakentias. The section from Agia Marina to the tunnel portal east of Doukissis Plakentias is underground.
It first opened, between Ethniki Amyna and Syntagma, on 28 January 2000, with Line 2. In 2012, construction works commenced for the final underground extension of Line 3 to Dimotiko Theatro via Piraeus, for completion by the end of the decade.

This is a list of stations on Line 3.
Dual voltage ROTEM-supplied stock with greater luggage space is used for services to Athens International Airport. Line 3 rail vehicles utilize 750V DC third rail current collection between Agia Marina and Doukissis Plakentias, changing to 25kV AC overhead catenary while operating on the Proastiakos suburban railway for access to/from the airport.
On March 1, 2012, a contract was signed between Attiko Metro S.A. and a joint venture for the construction of the extension of Line 3 from Aghia Marina to Piraeus, 7.6 km long with six stations. Upon completion in 2019, the extension will bring the Korydallos and Nikaia municipalities into the network's catchment area, serve approximately 132,000 passengers on a daily basis and will connect the port of Piraeus, the largest passenger port of Europe with the Athens International Airport in just 1 hour in total.Agia Varvara (2019)
