A refrigerator includes: a cabinet defining a storage space, a door that opens and closes the storage space, an evaporator generating cold air to thereby reduce a temperature of the storage space, a blowing fan circulating the cold air in the storage space, a grille panel provided at a rear side of the storage space and including a discharge port discharging the cold air into the storage space, and an ice maker disposed at a front side of the grille pan and including a guide duct guiding a flow of the cold air discharged from the discharge port. The guide duct provides a branched passage to thereby guide (i) a portion of the cold air discharged from the discharge port into the ice maker and (ii) remaining portions of the cold air to bypass the ice maker and into a space defined at a front side of the ice maker.
