An object of the present invention is to provide a technology by which a vehicle can be prevented from traveling in a manner in which path-tracking performance is impaired. This automatic steering control apparatus comprises a target locus acquisition unit which acquires a target locus to be the travelling locus of the vehicle; a target steering angle acquisition unit which, on the basis of the target locus, acquires a target steering angle to be the steering angle of the vehicle; a slideslip angle estimation unit which, on the basis of the target steering angle and the state of the vehicle, estimates a slideslip angle for when the vehicle travels with the target steering angle; and an automatic steering control unit. The automatic steering control unit discontinues automatic steering control and/or controls a steering amount adjustment gain for adjusting the target steering angle in a case where the estimated slideslip angle is a predetermined specified value or more.
