A method for controlling valve timing for an engine includes: classifying a plurality of control regions depending on an engine speed and an engine load; applying a maximum duration to an intake valve and controlling an exhaust valve to limit a valve overlap in a first region; controlling the intake valve and the exhaust valve to maintain the maximum duration in a second region; advancing an intake valve closing (IVC) timing and an exhaust valve closing (EVC) timing in a third region; approaching the IVC timing to a bottom dead center (BDC) in a fourth region; controlling a throttle valve to be fully opened, advancing an intake valve opening (IVO) timing before a top dead center (TDC), and controlling the IVC timing to be a predetermined value after the BDC in a fifth region; and controlling the throttle valve to be fully opened and advancing the IVC timing in a sixth region.
