A fuel injection control device for an internal combustion engine, includes a rotational speed sensor for detecting rotational speed of the internal combustion engine, intake air quantity sensor for detecting an air quantity taken into the internal combustion engine, atmospheric pressure sensor for detecting atmospheric pressure, and an engine control unit for estimating an inlet pipe pressure of the internal combustion engine from the detected rotational speed and intake air quantity, computing a fuel injection quantity fuel pressure correction coefficient according to a difference between the estimated inlet pipe pressure and the detected atmospheric pressure, and correcting a fuel injection quantity based on the computed fuel injection quantity fuel pressure correction coefficient.
