A vehicle-height adjusting system includes: vehicle-height adjusting actuators each for adjusting a vehicle height for a corresponding one of wheels; a pressure medium supplier for supplying a pressure medium from a tank to each of the vehicle-height adjusting actuators; and a vehicle height adjuster for adjusting the vehicle height for each wheel. The vehicle-height adjusting actuators include a left vehicle-height adjusting actuator and a right vehicle-height adjusting actuator. The vehicle height adjuster includes a supply amount controller configured to control the pressure medium supplier such that substantially the same amount of the pressure medium is to be supplied from the tank to the left vehicle-height adjusting actuator and the right vehicle-height adjusting actuator, when at least one of the wheels is in contact with an uneven road surface.
