The invention provides a commercial vehicle cab rear wall outer board which comprises a rear wall outer board body. A seal ring is adhered to the periphery of the rear wall outer board body, a first diversion groove is formed in the top of the rear wall outer board body and located on the inner side of the seal ring in the width direction, second diversion grooves (the lower ends penetrate through the bottom of the rear wall outer board body) are formed in two sides of the rear wall outer board body and located on the inner side of the seal ring in the height directions respectively, the upper ends of the second diversion grooves are communicated with the first diversion groove so as to form a door-shaped diversion groove, and the first diversion groove is in a shape with a higher middle and two lower ends. Multiple vertical diversion holes are formed in the top of the rear wall outer board body and communicated with the first diversion groove, and at least 1 mm gaps are reserved between the diversion holes and the bottom face of the seal ring. The first diversion groove is equal to the second diversion grooves in depth, and the depth is 1-3 mm. The door-shaped diversion groove, the diversion holes and the rear wall outer board body are integrally formed. By the adoption of the commercial vehicle cab rear wall outer board, the phenomenon that rainwater easily seeps into a trunk at the cab bottom inside a cab can be avoided.
