A refrigerator includes a main body having a storage compartment, first and second doors opening or closing the storage compartment, and a pillar configured to block cool air from leaking between the first and second doors. The refrigerator also includes a hinge that rotatably connects the pillar to the first door and a holder disposed on the storage compartment and configured to guide rotation of the pillar. The hinge includes a rotation shaft that enables the pillar to rotate with respect to the first door and a rotation restriction unit that is configured to contact the holder and, based on the contact with the holder, move the rotation shaft in a direction parallel to an extension direction of the rotation shaft. The rotation restriction unit selectively restricts the rotation of the pillar with respect to the first door.
