An ice making unit and a refrigerator having the same are disclosed. The refrigerator includes an ice making unit to make ice pieces. The ice making unit includes a plurality of ice making trays to form ice pieces, a lever part connected to the ice making trays to simultaneously rotate the ice making trays, and a stopper to prevent one of a pair of rotating shafts of each of the ice making trays from being rotated at a predetermined angle or more so that the ice making trays get twisted when the ice making trays are rotated. Accordingly, ice pieces can be separated from the ice making trays by operation of a single lever.
