Disclosed is an internal combustion engine control device. The control device is provided with an engine output shaft, a constant mesh starter, fuel injection valves, and a reduction correcting section. After automatic stop conditions are met, engine operation is restarted when restart conditions are met. At this time, the control device uses the aforementioned starter to rotationally drive the aforementioned engine output shaft, and restarts fuel injection by the aforementioned fuel injection valves when the aforementioned engine is in a transient state in which speed has been reduced to a speed at which the rotation of the aforementioned engine output shaft cannot restore the engine to autonomous operation but in which rotation has not completely stopped. When the aforementioned restart conditions are met, if the internal combustion engine is in the aforementioned transient state, the reduction correcting section correctively reduces the start-time fuel injection amount during engine operation restart compared with when rotation of the aforementioned output shaft is completely stopped.
