To improve exhaust emission by restraining uneven combustion inside a combustion chamber.
This fuel injection control device for internal combustion engine comprises: a first fuel injection valve arranged to a first inlet port to form flow to an inner periphery of a cylinder, and injecting a fuel of large grain diameter; a second fuel injection valve arranged to a second inlet port so as to form flow to an inner and outer peripheries of the cylinder, and injecting a fuel of small grain diameter; and a direct fuel injection valve for injecting fuel inside the cylinder. After the fuel is injected from the second fuel injection valve at end of an exhaust stroke, VIGOM injection by the direct fuel injection valve is performed, and then the fuel is injected from the first fuel injection valve, and thereafter, the fuel is injected from a fuel injection valve inside the cylinder at a top dead center or near a top dead center.
