Disclosed is an insulation structure for a liquefied gas storage tank with improved structural stability. According to one embodiment of the present invention, an insulation structure for a liquefied gas storage tank comprises: a foam insulation layer covering the outer surface of the storage tank for accommodating liquefied gas; a plurality of barriers provided to surround the outside of the foam insulation layer; a plurality of supports for supporting the plurality of barriers by separating the plurality of barriers from the outer surface of the foam insulation layer; and a powder insulator filled in a space between the outer surface of the foam insulation layer and the inner surface of the plurality of barriers. Each barrier may be provided with one side curved concavely toward the storage tank.
