A refrigerator includes a first refrigerator including a first cabinet and a second refrigerator including a second cabinet, and operating independently from the first refrigerator. A first connector is installed on the first cabinet; and a second connector is installed on the second cabinet to correspond to the first connector. The second connector is configured to be coupled to the first connector, such that in a state in which the first connector and the second connector are coupled to each other, a movement of the first cabinet in a first direction with respect to the second cabinet is allowed, and a movement of the first cabinet in a second direction with respect to the second cabinet is restricted, with the second direction being perpendicular to the first direction.
