A steering control device includes an electronic control unit. The electronic control unit controls operation of a steering-side motor so as to apply a steering reaction force that resists a steering operation input to the steering wheel. The electronic control unit computes an obstruction strike reaction force for regulating a steering operation that steers a steered wheel toward an obstruction. The electronic control unit generates determination information indicating that the steered wheel is struck by an obstruction. The determination information includes first determination information indicating that the left side of the steered wheel is struck by an obstruction, and second determination information indicating that the right side of the steered wheel is struck by an obstruction. The electronic control unit sets a direction in which the obstruction strike reaction force is applied based on the generated determination information.
