Jose Holebas' lone strike ensured the Republic of Ireland ended 2012 with a defeat as Greece triumphed at the Aviva Stadium.
The Olympiacos midfielder struck after 29 minutes, turning John O'Shea to fire into the bottom corner from the edge of the box.
Ireland had chances of their own with Robbie Brady and James McCarthy forcing saves from Orestis Karnezis, but Giovanni Trapattoni's youthful side could not find a way back into the game.
