PROBLEM TO BE SOLVED: To provide a vehicular steering control device capable of estimating the vehicular quantity of the state of high accuracy, and estimating the vehicular quantity of a state in an early stage before the saturation of the tire force. SOLUTION: The vehicular steering control device includes an angle detection means 15 for detecting the steering wheel angle of a vehicle, a vehicle speed detection means 11 for detecting the vehicle speed of a vehicle, a linear target road surface reaction torque computation means 23 for computing the liner target road surface reaction torque based on the steering wheel angle detected by the angle detection means 15 and the vehicle speed detected by the vehicle speed detection means 11, and a linear target road surface reaction torque correction means 24 having the frequency characteristic of the actual road surface reaction torque to the steering wheel angle to correct the linear target road surface reaction torque computed by the linear target road surface reaction torque computation means 23 based on the frequency characteristic.
