Greek National Road 17 (, abbreviated as EO17) is a single carriageway road in northwestern Greece. It connects Ioannina with Dodoni and the nearby ancient site of Dodona, via Bizani.
Ministerial Decision G25871 of 9 July 1963 created the EO17 from the old EO79, which existed by royal decree from 1955 until 1963, and followed the same route as the current EO17.
