A steering control device capable of causing a steering torque to follow a target steering torque when a driver holds a steering wheel for steering, and making an adjustment so that the steering wheel returns to a neutral position at an appropriate speed, when the driver releases his or her hands from the steering wheel. A motor is controlled based on a motor steering assist torque, which is a sum of a first steering assist torque, which is proportional to an integral value of a deviation between the target steering torque and the steering torque, and a second steering assist torque, which is proportional to a motor rotational angular velocity and acting in a direction of suppressing a return speed of the steering wheel when the steering wheel returns to the neutral position.
