A controller for internal combustion engine has an intake cam for low-load operation and an intake cam for high-load operation. The controller switches the intake cam used to open/close an intake valve and changes the phase angle of each intake cam according to load on the internal combustion engine. The controller changes the phase angle at start of opening of intake valve by the intake cam for low-load operation in lag angle direction within a predetermined range as load on the internal combustion engine increases, and changes the phase angle at start of opening of intake valve by the intake cam for high-load operation in lead angle direction within the predetermined range as load on the internal combustion engine increases. Switching between the two intake cams is performed where the phase angles of the intake cams are controlled to predetermined phase angles on a lag angle side.
