The present invention relates to a transformable desk which can be used by multiple users. The transformable desk comprises multiple top plates, side legs formed on one side of the top plates, and a central supporting leg which is coupled to the other side of the top plates to support the top plates. The side legs can be folded downward from the top plates, and the top plates are overlapped in a row. The overlapped top plates can be unfolded by being rotated around the central supporting leg.
