A fuel injection control device learns a port injection learning value and a direct injection learning value separately for each of learning regions that are divided according to the engine operating state. It is assumed that a port injection learning condition and a direct injection learning condition are both satisfied in a learning region in which neither the learning of the port injection learning value nor the learning of the direct injection learning value has been completed. In such a situation, the fuel injection control device executes the port injection learning process if the ratio of the port injection amount is less than the ratio of the direct injection amount, and executes the direct injection learning process if the ratio of the direct injection amount is less than the ratio of the port injection amount.
