At the 2008 Summer Olympics in Beijing, Gunenc qualified for the second time in the women's 200 m butterfly by eclipsing a FINA B-standard of 2:15.32 from the Toyota Grand Prix four months earlier in Columbus, Ohio. Swimming in heat one, Gunenc set a Turkish record in a tech bodysuit at 2:14.44 to chase Norway's Ingvild Snildal for second place by just a fingertip (0.09 seconds), but failed to advance to the semifinals with a thirty-second overall finish.
