Control device for internal combustion engine

The present invention addresses the problem of providing a control device for an internal combustion engine capable of improving exhaust gas characteristics and idling stability by specifying a cylinder in which misfire has occurred and suppressing misfire of the cylinder to stabilize a combustion state. In this control device for an internal combustion engine, a rotational speed parameter (time parameter CRME) indicating the rotational speed of an internal combustion engine (3) having a plurality of cylinders is detected, and on the basis of the rotational speed parameter detected in each combustion stroke of the plurality of cylinders, single misfire, which is misfire per ignition, is detected for each cylinder (steps 2-7, 9). The number of misfire detection times is counted for each cylinder as a misfire counter value CMF (k) (steps 8, 10), on the basis of the misfire counter value CMF (k), whether or not misfire has occurred in the cylinder is determined (steps 11 to 12), and the ignition timing IGLOG of
