The A8 motorway, also known as the Olympia Odos (Greek: Ολυμπία Οδός), is a toll motorway in southwestern Greece, which connects Athens with Patras via Corinth, spanning a total of 215 km (134 mi). The future, currently under construction, Patras - Pyrgos motorway is expected to open by the end of 2025. The motorway will eventually extend to Tsakona near Kalamata, connecting with the A7 Moreas Motorway.

The motorway replaces Greek National Road 8A, which has been upgraded to modern motorway standards. The completion date was scheduled for 2014. Since April 2017, the entire motorway from Eleusis to Patras is fully operational.
