A fuel injection control device is configured to suppress the effect of pressure pulsation occurring inside the accumulator section of an engine due to a first fuel injection and thereby accurately control the fuel injection quantity in an engine configured to execute a plurality of fuel injections per cycle. When the fuel injection quantity for a second injection executed after a first injection is set, the fuel injection interval is detected and the fuel injection quantity is revised based on the fuel injection interval. The amount of time from the end of the first injection (e.g., a pilot injection) to the start of the second injection (e.g., a main injection) is used as the fuel injection interval.
