An apparatus and method for controlling steering of a vehicle, the apparatus including: a saturation rear wheel lateral offset angle acquisition unit that acquires a saturation rear wheel lateral offset angle when a rear wheel lateral force is saturated during steering of the vehicle from an operation state quantity and a motion state quantity; an actual rear wheel lateral deviation angle calculation unit that calculates an actual rear wheel lateral deviation angle from the motion state quantity; a vehicle body lateral deviation angular velocity calculation unit that calculates a vehicle body lateral deviation angular velocity from the motion state quantity; a first correction amount calculation unit that calculates, from the vehicle speed, a first correction amount for correcting a comparison value between the rear wheel lateral offset angle and the actual rear wheel lateral offset angle during saturation; a second correction amount calculation unit that calculates, from the vehicle speed and the first correction amount, a second correction amount for correcting the vehicle body lateral deviation angular velocity; and a target yaw amount calculation unit that calculates a target lateral yaw amount from the rear wheel lateral offset angle during saturation, the actual rear wheel lateral offset angle, the comparison value corrected by the first correction amount, and the vehicle body lateral offset angular velocity corrected by the second correction amount.
