A steering control device capable of transmitting road surface state to a driver is provided. An ideal vehicle model computes first spring reaction force torque based on a target pinion angle and second spring reaction force torque based on at least lateral acceleration as components of a spring component of a steering assist force. The ideal vehicle model combines the first and second spring reaction force torques with specified proportions of use to compute the spring component. The ideal vehicle model decides the proportions of use of the first and second spring reaction force torques on the basis of a distribution gain set in accordance with the difference value between the first and second spring reaction force torques. The ideal vehicle model increases the proportion of use of the second spring reaction force torque as the difference value between the first and second spring reaction force torques is increased.
