Disclosed herein is a refrigerator which includes: a main body having an opening, and including a storage chamber therein; a door configured to open or close the opening; a camera unit disposed in the door, and configured to photograph the storage chamber, wherein the camera unit faces the storage chamber selectively by interworking with opening or closing of the door. With this configuration, it may look in the storage chamber of the refrigerator without opening any door and minimize exposure of the camera unit to the outside.
