A steering control apparatus for a motor vehicle with steerable front and rear road wheels keeps electric power supplied to an electric motor for turning the rear road wheels, at a desired value even when the voltage of a vehicle-mounted battery for energizing the motor fluctuates. The steering control apparatus includes a battery mounted on the motor vehicle, an electric motor energizable by electric power supplied from the battery for applying power output to at least a steering mechanism for turning the rear road wheels, detecting means for detecting the voltage of the battery, and a motor control unit for controlling operation of the electric motor. The motor control unit includes determining means for determining a control signal for the electric motor, correcting means for correcting the control signal with a battery voltage detected by the detecting means, and driver means for energizing the electric motor by supplying the electric motor with the electric power from the battery based on the corrected control signal.
