A refrigerator includes a body, a refrigerating compartment provided inside the body, a freezing compartment positioned at a lower portion of the refrigerating compartment and provided inside the body, an ice-making compartment provided inside the body and provided with an insulated space that is separated from the refrigerating compartment and the freezing compartment, and an ice-making compartment door to insulate the ice-making compartment from an outside and rotatably installed at the body as to open/close the ice-making compartment. Cooling efficiency is improved by completely separating the ice-making compartment from the freezing compartment and the refrigerating compartment, and user convenience is improved by separately installing the ice-making compartment door.
