The invention discloses a cigarette carton stacking device. The device comprises a hopper, a first material pushing mechanism, a stacking component and a second material pushing mechanism. A material carrying plate is arranged on the hopper, a containing groove extending in the height direction of the hopper is formed inside the hopper, a feed opening of the containing groove is formed at one side of the material carrying plate, and a discharge opening is formed in one side of the containing groove; the stacking component comprises a base plate, two clamping plates and a third driving mechanism, the base plate is arranged at the outer side of the discharge opening, and the two clamping plates are arranged at the two sides of the base plate. According to the cigarette carton stacking device, structures of all steps are independent of one another, cigarette carton superposing is not influenced by cigarette carton separating, cigarette carton separating and cigarette stacking are not influenced by cigarette carton superposing, cigarette carton superposing is not influenced by cigarette carton stacking, through the decomposition, work cycles of all the steps are greatly shortened, and production efficiency of an enterprise is improved.
