A refrigerator includes a cabinet defining an upper storage space, a lower storage space and a machine room provided at a lower end of the cabinet. A dispenser is provided in an upper door of the upper storage space to dispense water or liquid, and an ice maker is provided inside the upper door to make ice. A pump assembly is provided inside the machine room to pump water through a water supply passage from a water tank to the dispenser and the ice maker. The water supply passage extends downward from the water tank after passing through a rear surface of the cabinet to connect to the pump assembly inside the machine room and extends upward from the pump assembly and passes through an upper surface of the cabinet to connect to the dispenser and the ice maker.
