A shock-absorbing caster dock includes a dock shell and a caster assembly. The dock shell is fastened to the bottom of a luggage for holding the caster assembly. The caster assembly includes a wheel, two side levers located on two sides of the wheel, a shaft running through the upper portion of the two side levers to pivotally engage with a side wall, and an elastic element coupling on the shaft. The elastic element has a middle portion bucking the side wall and two ends latching and pressing the side levers to provide elasticity for the side wall to withstand the gravity force of the luggage and absorb vibrations.
