To provide a vehicle steering device capable of stabilizing behavior of a vehicle when traveling backward.A vehicle steering device includes a reaction force device configured to apply steering reaction force to a wheel, a drive device configured to turn tires in accordance with steering of the wheel, and a control unit configured to control the reaction force device and the drive device. The control unit includes a turning ratio map unit configured to set a turning ratio gain in accordance with the vehicle speed of a vehicle, and a target turning angle generation unit configured to generate a target turning angle by multiplying the steering angle of the wheel by the turning ratio gain. The turning ratio gain at backward traveling of the vehicle is equal to or larger than the turning ratio gain at forward traveling of the vehicle.
