The present invention relates to a refrigerator having a dispenser. In the present invention, the dispenser is provided in a concave portion of a door to be exposed toward a front surface of the door. A water tank is installed between a rear surface of the dispenser and a door liner defining a rear surface of the door. The water tank stores the water delivered from an external water supply source while the water in maintained at a relatively low temperature and then discharges the water to the outside through the dispenser. Furthermore, in the present invention, a nozzle, through which the water is discharged from the water tank, is directly connected to a drainpipe of the dispenser, so that users may always take out the water maintained at a constant temperature.
