The invention relates to the field of vehicles, and provides a ventilation grille, a vehicle door and a vehicle. The ventilation grille comprises a plurality of grille blades and sound insulation pads, the grille blades are arranged at intervals in the vertical direction, the lowest point of the upper grille blade and the highest point of the lower grille blade in every two adjacent grille blades are arranged at intervals in the vertical direction, every two adjacent grille blades define a ventilation channel, and the ventilation channel communicates with the cab and the environment outside the automobile. And in the direction from outside to inside, each grating blade is arranged in a downward inclined mode, a sound insulation pad covers a ventilation opening, located on the outer side, of each ventilation channel, and the upper end of each sound insulation pad is connected with the top of the corresponding ventilation channel. According to the ventilation grille provided by the embodiment of the invention, the effect of quick pressure relief can be achieved when the vehicle door is closed, the transmission of noise can be effectively blocked, and the sound insulation effect is improved.
