There is provided a fuel injection control apparatus for an in-cylinder injection internal combustion engine that limits increases in the amount of discharged PMs and the amount of oil dilution when a demanded amount of injection is changed while divisional injection is being performed. The control apparatus is provided for an internal combustion engine having a fuel injection valve for injecting fuel into a combustion chamber of the internal combustion engine, a fuel pump for feeding fuel to the fuel injection valve by pressuring the fuel, and a fuel storage chamber storing fuel to be supplied to the fuel injection valve. In the engine, divisional injection control including a plurality of fuel injections executed in one cycle is performed. When a demand for making a change in the amount of fuel supplied per cycle occurs, changes in the amount of fuel injection are made according to injection times.
