A steering device (1) includes: a steering member (4) that is provided in a vehicle (2) and configured to be rotationally operated; an actuator (8) that generates a torque assisting a steering operation on the steering member (4); a detection device (9) that detects a torque applied to a steering shaft portion (5) that rotates together with the steering member (4); and a steering control device (11) that performs vibration suppression control to suppress vibrations transmitted to the steering member (4) by adjusting a torque generated by the actuator (8), on a basis of a detected torque that is a torque detected by the detection device (9). The steering control device (11) controls the actuator (8) such that a torque of a frequency band in a first predetermined range, which corresponds to the detected torque is not suppressed.
