Provided is a control apparatus for an internal combustion engine, which can adequately perform the control of a fuel injection amount even when an abnormality, a disconnection or the like of a fuel pressure sensor occurs and thereby accurate fuel pressure information is not able to be obtained. A fuel injection valve (26) is provided which is capable of directly injecting fuel into a cylinder. If a target fuel injection amount is smaller than a minimum fuel injection amount that is minimum and is capable of injecting during one opening and closing operation of the fuel injection valve (26), the start timing of fuel injection is set within a period in which an exhaust valve is opened during an exhaust stroke.
