In a vehicle vibration-damping controlling apparatus for executing vibration-damping control to control a power source loaded on a vehicle to suppress sprung vibration of the vehicle, a control amount of the vibration-damping control is changed based on a judgment target amount that is used in judging control and variable accompanied by an execution of the vibration-damping control. Therefore, since the control amount of the vibration-damping control is changed based on the judgment target amount, it is possible to allow the vibration-damping control to coordinate with various pieces of judging control related to the power source and appropriately execute the vibration-damping control.
