Greek National Road 64 (, abbreviated as EO64) is a national road in the regional unit of Achaea, Greece. Created in 1963 from a former national airport road, the EO64 is a branch of the EO9 from Kato Achaia to Araxos, north of Patras Araxos Airport.
The EO64 is officially defined as a branch of the EO9, running between Kato Achaia to the east and Araxos to the west. It passes through the villages of Niforeika, and Lakkopetra. The road between Araxos and Patras Araxos Airport is part of Achaea Provincial Road 39.
Ministerial Decision G25871 of 9 July 1963 created the EO64 from the old EO91, which was an national airport road that existed by royal decree from 1955 to 1963. In 1995, the EO64 became part of the secondary national road network.
