Abstract: A fuel injection control device is applied to an internal combustion engine including a fuel injection valve and causes a valve body to be in a valve open state accompanying an energization of the fuel injection valve to inject fuel. The fuel injection control device acquires a dynamic parameter. The fuel injection control device acquires an injection amount parameter. The fuel injection control device calculates, based on the dynamic parameter, a dynamic correction value. The fuel injection control device calculates, based on the injection amount parameter, an injection amount correction value. The fuel injection control device corrects a fuel injection using the dynamic correction value and the injection amount correction value.
