National Road 12 (Greek: Εθνική Οδός 12, abbreviated as EO12) is a single carriageway road in northern Greece. It connects Thessaloniki with Kavala, passing through Serres and Drama. It also serves traffic heading towards the north, to the Greek/Bulgarian border. The section between Thessaloniki and Serres forms part of the Ε79 route. Part of the GR-12 has been replaced by the new A25 motorway (Thessaloniki - Serres) and the A2 motorway (Egnatia Odos).
