PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine for optimally controlling the internal combustion engine by utilizing the pulsation of pressure in intake pipe for easily estimating a cylinder filled air amount for each cylinder. SOLUTION: The control device comprises a throttle passing air amount calculating means 19 for calculating a throttle passing air amount mt for air to pass through a throttle valve 18, an extra air amount calculating means for calculating an extra air amount for each cylinder equivalent to a drop amountΔPmdwn of pressure in the intake pipe with the opening of an intake valve corresponding to each cylinder, a cylinder filled air amount estimating means for estimating a cylinder filled air amount Mti for each cylinder in accordance with the throttle passing air amount detected by the throttle passing air amount detecting means and the extra air amount calculated by the extra air amount calculating means, and an engine control means for controlling the internal combustion engine in accordance with the cylinder filled air amount for each cylinder estimated by the cylinder filled air amount estimating means.
