Disclosed is a liquefied gas storage tank. According to one embodiment of the present invention, the liquefied gas storage tank comprises: a first barrier surrounding an accommodation space of the liquefied gas; a first insulation panel insulating the liquefied gas by surrounding the first barrier from the outside and including a first lower reinforcing plate and a first insulation member coupled to the first lower reinforcing plate; a second barrier surrounding the first insulation panel; a second insulation panel insulating the second barrier from the outside by surrounding the same; and a panel coupling portion coupling the first insulation panel and the second insulation panel. The panel coupling portion comprises: a projection member coupling to the second insulation panel and extending towards a through hole formed in the first insulation member while penetrating the second barrier and the first lower reinforcing plate; and a coupling portion coupled to the projection member and coupling the first insulation panel and the second insulation panel. The coupling portion comprises: a nut member fastened to the projection member; a washer member inserted into the projection member to be provided between the nut member and the first lower reinforcing plate; and a buffer member formed on a lower surface of the washer member and reducing stress acting on the first lower reinforcing plate. According to the present invention, the liquefied gas storage tank is capable of reducing shear stress and damage to the lower reinforcing plate of the first insulation panel when the first insulation panel and the second insulation panel are fastened by a fixing bolt and a nut.
