A steering control apparatus prevents interference between a steering operation of a driver and a steering control operation of the steering control apparatus by detecting a steering operation so as to decrease an amount of the steering control operation when the steering operation is performed by the driver. A guide line provided on a vehicle moving lane on which the vehicle is moving is recognized so as to set a target position on the vehicle moving lane based on a result of recognition of the guide line. A steering control operation is performed so that the vehicle moves to trace the target position. An amount of each component of a steering operation applied to a steering wheel is detected by a steering angle sensor and a steering torque sensor. An amount of the steering control operation is corrected so that the amount of the steering control operation is decreased in accordance with the amount of each component of the steering operation.
