An electronic control unit sets a target valve actuation parameter in accordance with an operating state of an internal combustion engine, and controls a variable valve actuation mechanism such that an actual valve actuation parameter of an intake valve becomes equal to the target valve actuation parameter. The variable valve actuation mechanism changes a valve actuation parameter of the intake valve. From before an initial fuel injection is performed to when a starting process of the engine is completed, the electronic control unit sets the target valve actuation parameter to an engine starting valve actuation parameter at which the valve closing timing of the intake valve coincides with or is close to a bottom dead center of the intake valve.
