A method for controlling valve timing is provided for an engine including a continuous variable valve duration device disposed on an intake valve side, and a continuous variable valve duration device and continuous variable valve timing device disposed on an exhaust valve side. The method includes: classifying first, second, third, fourth, and fifth control regions depending on an engine speed and an engine load; applying a maximum duration to an intake valve and controlling a valve overlap in the first control region; applying the maximum duration to the intake valve and exhaust valve in the second control region; controlling a manifold absolute pressure (MAP) of an intake manifold to be maintained consistently in the third control region; controlling a wide open throttle valve (WOT) and retarding an exhaust valve opening (EVO) timing in the fourth control region; and controlling the WOT and retarding an intake valve closing (IVC) timing in the fifth control region.
