A refrigerator includes a storage chamber for storing food; an ice making compartment provided at an upper side corner of the storage chamber; and two shelves provided between a sidewall of the ice making compartment and a sidewall of the storage chamber opposite to the sidewall of the ice making compartment. The two shelves include a rotatable shelf and a horizontal shelf mounted between the sidewall of the storage chamber and the rotatable shelf and configured to be adjustable vertically upwards and downwards independently of the rotatable shelf. The rotatable shelf, while maintaining the vertical position, forms a vertical space for keeping food having a great height and stored on a shelf provided below the rotatable shelf. The rotatable shelf and the horizontal shelf form a horizontal space for keeping food having a great width when the horizontal shelf and the rotatable shelf in the horizontal position are horizontally aligned.
