Greek National Road 8 (Greek: Εθνική Οδός 8, abbreviated as EO8, common name: old Athens-Patras national road) is a single carriageway with at-grade intersections in the Attica, Peloponnese and West Greece regions. It connects Athens with the cities of Corinth and Patras. Since the 1960s it has been replaced for most of its length with the National Road 8A, a limited-access toll road that bypasses most towns, as the major route to the Peloponnese. The National Road 8A is gradually being upgraded to a motorway, the Olympia Odos (A8).
National Road 8 passes along the northern coast of the Saronic Gulf, through the Isthmus of Corinth and further, along the southern coast of the Gulf of Corinth, and ending in downtown Patras. It runs through five regional units: Central Athens, West Athens, West Attica, Corinthia and Achaea. Since the opening of National Road 8A it is mainly used for local traffic in the coastal towns.
Additionally, the EO8a and A8 "Olympia Odos" runs parallel to the EO8 from Patras to Eleusis, although it bypasses many villages and towns that the EO8 directly serve. The remaining sections of the EO8a (between Corinth and Rio) will be upgraded to be part of the A8, and the EO8 will become a non-motorway detour.
Apart from the EO8a and A8, the EO8 has connections with (from east to west) the EO1, EO56, A1, EO58, EO3, EO7, EO31, EO5, EO33 and EO9: the EO58, a short airport road to the Eleusis Airbase, also branches off from the EO8.
