The present invention relates to a method for preparing a superabsorbent polymer that progresses dry mixing of fine powders and a specific powder type of polymer binder when reassembling fine powders generated during the preparation process of a superabsorbent polymer, and thus obviates the necessity for a moisture drying process after reassembling fine powders, thereby reducing thermal losses, improving productivity, and obtaining a superabsorbent polymer having excellent basic absorption properties, and a superabsorbent polymer prepared by the method.
