The present invention relates to an automatic opening/closing apparatus for a dump truck loading box door, which is able to allow goods to be discharged without giving too much force to the vehicle by letting a rear door open sufficiently as a loading box is lifted upwards. The dump truck loading box door is installed on an upper side of a frame of a dump truck, and has a front unit which is vertically movable, thereby opening/closing a rear door of the loading box which is installed on a front side to tilt towards a rear side. The automatic opening/closing apparatus for the dump truck loading box door comprises: a guide plate installed on an upper side of the rear door to guide the opening/closing; two door hinge units arranged on an upper rear side of side walls on both sides of the loading box to rotatably support the guide plate; and an opening/closing control member having one end unit connected to a first connection ring arranged on the guide plate, and having the other end unit connected to a second connection ring arranged on the frame, and controlling the opening angle of the rear door.
