Provided are: a steering system that is capable of, with a simple apparatus, enhancing maneuvering stability and safety when turning a vehicle and that is capable of enhancing the performance in small-radius turning by allowing all wheel angles to be freely steered independently on the left and right sides in accordance with a vehicle situation; and a vehicle provided with this steering system. A steering system (101) is provided with: a first steering apparatus (11) that causes front wheels to be steered in accordance with a steering-amount instruction; second steering apparatuses (1501, 1502) that cause the left and right wheels to be separately steered on the front side and the rear side, respectively, by being driven by steering actuators; and a vehicle information detecting unit (110) that detects vehicle information. The second steering apparatuses (1501, 1502) are provided with control units (150b) that separately control the steering actuators of target wheels on the basis of the vehicle information and steering angles of the other wheels. The control units (150b) control the respective steering actuators so as to adjust the toe angles of the left and right wheels on the front side and the rear side in accordance with the vehicle speed and the steering angles.
