An optical axis control apparatus includes: an optical axis controlling unit for calculating, during stop of the vehicle, a pitch angle using an acceleration sensor provided in a vehicle and controlling, using the pitch angle, optical axis angles of headlights provided in the vehicle; and a rolling motion determination unit for determining, when the vehicle has started traveling, whether there has been a rolling motion during the stop of the vehicle. When the pitch angle has been changed during the stop of the vehicle and the rolling motion determination unit determines that the rolling motion exists, the optical axis controlling unit corrects, when the vehicle has started traveling and the rolling motion has been terminated, the amount change in pitch angle, using the amounts of correction set for each roll angle, and controls the optical axis angles using the corrected pitch angle.
