Disclosed is an insulation structure for a liquefied gas storage tank, capable of maintaining a stable structure in response to thermal deformation of the storage tank and maintaining insulation performance. According to an 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 leakage channel formed on an inner surface of the foam insulation layer in contact with an outer surface of the storage tank and provided as a passage through which liquefied gas leaking from the storage tank moves; a plurality of barriers provided to surround the outside of the foam insulation layer; and a plurality of supports for supporting the plurality of barriers by separating the plurality of barriers from an outer surface of the foam insulation layer. The leakage channel may be provided with an open cell fiber in which a plurality of pores are formed to absorb liquefied gas leaking from the storage tank.
