A steering control device includes a microcomputer. The microcomputer is configured to calculate a torque command value that is a target value of a motor torque, set a restricting value that is an upper limit of an absolute value of the torque command value, restrict the absolute value of the torque command value to be equal to or less than the restricting value, control driving of a motor such that the motor torque follows the restricted torque command value, calculate a steering angle restricting value that decreases based on an increase of an absolute value of a rotation angle, and an absolute value of an angular velocity, when the absolute value of the rotation angle of the rotary shaft exceeds a steering angle threshold, and set the restricting value to be a value equal to or less than the steering angle restricting value.
