A fuel injection control device for an engine includes an ECU. The ECU is configured to: change a port injection ratio in accordance with an operation state of the engine; execute correction of the total fuel injection amount by reflecting a correction amount in a basic fuel injection amount depending on the operation state when the port injection ratio is changed; and when the ECU changes the port injection ratio and calculates a second correction amount that is the correction amount having one of the positive and negative values during the execution of the correction based on a first correction amount that is the correction amount having the other one of the positive and negative values, limit reflection of the first correction amount in the basic injection amount.
