A refrigerator includes a cabinet, a main-door, the main-door, a sub-door, a restraint device that protrudes from a rear surface of the sub-door, a latch device located at the main-door and configured to selectively restrict movement of the restraint device, and an operation device located at the sub-door and configured to release the restraint device from the latch device. The latch device includes a latch configured to restrict movement of the restraint device from the latch based on rotation of the latch, a stopper configured to engage a side of the latch and limit movement of the latch, a pusher configured to push the stopper to cause the stopper to rotate, and an elastic member connected to the latch and to the stopper. The latch is configured to, based on rotation of the stopper, rotate and release restraint between the latch and the stopper.
