Disclosed is a refrigerator having a dispenser, including a main body having a cooling chamber and a door for selectively shielding the cooling chamber. The refrigerator also includes a container accommodating unit and a communication chute that passes through a front surface of the door and guides content to a dispensing cavity defined by the container accommodating unit. The refrigerator further includes an obstruction unit disposed in the container accommodating unit, and movable, about a plane perpendicular to the front which content guided by the communication chute is relatively obstructed by the obstruction unit and a second position in which content guided by the communication chute is relatively unobstructed by the obstruction unit.
