Ireland weathered the early storm from Turkey before getting into the game themselves, and they almost found the opening goal in the seventh minute as Stephen Ward flashed a volley narrowly wide.
They came even closer to taking the lead eight minutes later as Shane Long saw an initial effort saved by Onur Kivrak before a second attempt was cleared off the line.
Ireland looked for a response before half time but could only test the keeper once more, with James McClean firing a well-struck effort straight at Kivrak.
The visitors doubled their advantage with 15 minutes of the match remaining as once again they hit the hosts on the break, this time Tarik Camdal finishing the move having only just come on as a sub.
The hosts had a glorious chance to level the scores in the 86th minute when Daryl Murphy latched on to McClean's cross, only to direct his header straight at the keeper.
They couldn't find the equaliser in the closing stages, however, as Turkey held out for the victory.
