The invention discloses an automobile door drainage device. The automobile door drainage device is characterized by comprising an automobile door metal plate; a drainage hole is formed in the automobile door metal plate; a one-way valve blanking cap is arranged in the drainage hole and fixed to the portion, on the outer side of the drainage hole, of the automobile door metal plate through at least two clamping mechanisms. Each clamping mechanism comprises a first clamping head and a second clamping head, wherein the first clamping head and the second clamping head form a clamping groove. When the one-way valve blanking cap is clamped with the automobile door metal plate, the side edge of the drainage hole is clamped into the clamping grooves. The automobile door drainage device has the remarkable effects that the structure is simple and practical, when no liquid flows through, the blanking cap achieves the sealing effect, and the influences on the NVH performance of an automobile are avoided; when liquid flows through, the liquid flows out of the automobile door metal plate, the liquid is drained, it is guaranteed that no liquid is accumulated in the automobile door metal plate, and corrosion of the accumulated liquid to the automobile door metal plate is avoided.
