Line 3 of the Athens Metro is a rapid transit line that runs from Dimotiko Theatro in the west to Doukissis Plakentias or Athens Airport in the east, via Syntagma. Most Line 3 trains start or terminate at Doukissis Plakentias: a through service to the Airport leaves once every 36 minutes, and shares most of the extended route with the Athens Suburban Railway. It runs for 47.3 kilometres (29.4 mi), making it the system's longest line.

Line 3 provides a direct albeit infrequent service between the Port of Piraeus with the Athens International Airport, a journey that takes up to 59 minutes. The line between Dimotiko Theatro and Doukissis Plakentias is underground, and the shared section with the Athens Suburban Railway towards the Airport is a surface-level median of the A6 and A64 motorways.

It first opened, between Ethniki Amyna and Syntagma, on 28 January 2000, with Line 2. In 2012, construction works commenced for the latest underground extension of Line 3 to Dimotiko Theatro via Piraeus which was completed on 10 October 2022.
