A steer-by-wire steering system includes a controller configured to execute a steering control process and a determining process of determining a converted operation amount by converting an actual wheel steering amount to an operation amount of an operation member based on an inverse of a steering gear ratio. In the determining process, when the steering gear ratio abruptly changes, the controller converts a gap of the converted operation amount generated at a time point of occurrence of the abrupt change to a gap of the wheel steering amount to grasp a converted steering amount offset value. While gradually decreasing the converted steering amount offset value, the controller thereafter re-converts the converted steering amount offset value to the gap of the converted operation amount based on the inverse of the steering gear ratio to determine a converted operation amount correction value and corrects the converted operation amount based on the value.
