A pedestrian protection apparatus includes a collision prediction unit which predicts a collision of a vehicle with a pedestrian existing forward of the vehicle, a grille which is disposed on a front surface of the vehicle so as to be inclined while rising toward the rear and attached to the vehicle in a state where an upper end portion of the grille is forwardly advanceable, and an actuator mechanism which causes, when the collision prediction unit predicts the collision of the vehicle with the pedestrian, the grille to be moved in such a manner that the upper end portion of the grille is advanced forward by a forward advancing amount greater than that of a lower end portion of the grille.
