PROBLEM TO BE SOLVED: To enhance the vehicular convergence while enhancing the steering convergence. SOLUTION: A vehicle steering control device (10) has first calculation means (30) for calculating a basic steering assistance force (AT) based on the steering torque (MT) corresponding to the steering operation by an occupant of a vehicle, acquisition means (30) for acquiring respective lateral forces (F<SB>f</SB>, F<SB>r</SB>) of front wheels (5, 6) and rear wheels (7, 8), second calculation means (30) for calculating, based on the lateral force on the rear wheels, a first steering correction force that reduces the basic steering assistance force and also calculating, based on the lateral force on the front wheels, a second steering correction force that increases the basic steering assistance force, and steering force application means (10) for applying the target steering assistance force (T) to the vehicle, the target steering assistance force being obtained by adding the first and second correction steering forces to the basic steering assistance force.
