A coordinate obtaining unit of an automatic steering control apparatus obtains a subject-vehicle coordinate point indicating a current position of a subject vehicle, and a target coordinate point indicating a target position of the subject vehicle. A subject-vehicle state quantity obtaining unit obtains a subject-vehicle state quantity indicating a traveling state of the subject vehicle. A target trajectory determining unit calculates an interpolation coordinate point for interpolating between the subject-vehicle coordinate point and the target coordinate point or between a target coordinate point previously obtained and a target coordinate point subsequently obtained, and determines a target trajectory of the subject vehicle based on the interpolation coordinate point. A steering controller controls a steering control device of the subject vehicle so that the subject vehicle travels following the target trajectory, based on the subject-vehicle state quantity and the target trajectory.
