The invention provides a vehicle door reinforcing piece. The vehicle door reinforcing piece comprises a vehicle door lower beam, a vehicle door stopper reinforcing piece, a vehicle door inner skin and a vehicle door lower beam front support. The vehicle door lower beam front support is in an L shape. Two installation faces serve as the two edges of the L shape. One installation face is welded to the corresponding position, provided with a vehicle door hinge, of the vehicle door stopper reinforcing piece, wherein screw holes used for being connected with the vehicle door hinge are formed in the installation face and overlap screw holes used for installing the vehicle door hinge on the vehicle door stopper reinforcing piece. The other installation face of the vehicle door lower beam front support is welded to the front portion of the vehicle door lower beam. The vehicle door lower beam front support is additionally arranged between an existing stopper reinforcing piece and the vehicle door lower beam, and therefore the effect of reinforcing the vehicle door hinge installation portion can be achieved, and the anti-collision performance of a vehicle door can also be improved.
