A control device for a variable valve actuation system includes: an engine valve; a variable valve actuation mechanism that variably controls a valve timing of the engine valve and at least one of a valve operating angle and valve lift of the engine valve; a variable setting unit that variably sets a control range, in which at least one of the valve operating angle and the valve lift is controlled by the variable valve actuation mechanism, on the basis of the valve timing; a detecting unit that detects a plurality of valve timings of the engine valve in different modes in such a manner that the control range is changed; and a control range setting unit that variably sets the control range using one of the plurality of detected valve timings.
