The Klokova Tunnel (Greek: Σήραγγα Κλόκοβας) is a tunnel on the A5 motorway (Ionia Odos), western Greece.

It is built in order for the new motorway to bypass the Klokova mountain, which, until recently, was traversed by the narrow Greek National Road 5.

Works began in March 2015 and were completed with the opening of the tunnel on 12 April 2017.
