<P>PROBLEM TO BE SOLVED: To provide a fuel injection control device, injecting fuel at appropriate injection timing. Ž<P>SOLUTION: In the fuel injection control device 10 controlling injection of fuel to an engine 1, a fuel injection valve 6 injects the fuel supplied from a common rail 13 accumulating the fuel supplied by a high-pressure pump P2. An ECU 2 gives an injection instruction to the fuel injection valve 6, based on states detected by a fuel pressure sensor 37 detecting the pressure of the fuel and a fuel temperature sensor 35 detecting a temperature of the fuel. A fuel injection amount by the fuel injection valve 6 is calculated from a fluctuation value of the fuel pressure in execution of fuel injection by the fuel injection valve 6, the injection timing suitable for a delay time from the injection instruction to the execution of the fuel injection is controlled according to the fuel temperature or the fuel pressure.
