Disclosed is a variable spoiler apparatus of a rear bumper for a vehicle, which is housed at a lower side of the rear bumper, and is drawn out to the lower side when in use to control an air current. Therefore, driving stability and aerodynamic performance can be improved. The variable spoiler apparatus includes a linkage device, installed on a bumper back beam, and varies in length in an up-down direction during rotation. A spoiler is coupled to the linkage device and is able to move in the up-down direction by the rotation of the linkage device. A first drive device is installed on the bumper back beam. The first drive device is provided with a first rotary shaft coupled to the linkage device to transmit a rotational force. A guide is rotationally installed on the bumper back beam and is able to extend in the up-down direction. A second drive device is coupled to the guide so as to be movable in the up-down direction. When the second drive device is operated, the spoiler is tilted by length variation operation of a length-variable unit.
