The present invention relates to a liquefied gas storage tank and a ship including the same. The liquefied gas storage tank of the present invention is a liquefied gas storage tank provided on a hull and storing cryogenic substances, comprising: a primary barrier made of a metal material to form an accommodating space for accommodating the cryogenic material; a primary insulating wall provided on the outside of the primary barrier; a secondary barrier provided on the outside of the primary insulating wall; and a secondary insulating wall provided on the outside of the secondary barrier and fixed to the hull. The primary insulating wall includes a primary insulating material installed between the primary barrier and the secondary barrier, and a primary plywood installed between the primary barrier and the primary insulating material. The secondary insulating wall includes a secondary insulating material installed between the secondary barrier and the hull, and a secondary plywood installed between the secondary insulating material and the hull. The primary insulating wall includes a connection insulating wall provided in a space between the adjacent fixed insulating walls in a state in which unit elements formed by laminating fixed insulating walls that are part of the secondary insulating wall, the secondary barrier, and the primary insulating wall are arranged adjacent to each other. The connection insulation wall includes a connecting insulating material installed between the primary barrier and the secondary barrier, a connecting plywood installed between the primary barrier and the connecting insulating material, and an auxiliary insulating plate installed between the connecting insulating material and the secondary barrier. An object of the present invention is to provide the liquefied gas storage tank that is designed to reduce the low-temperature burden and sloshing burden of the secondary barrier while maintaining the mechanical strength of the secondary barrier at a certain level, and the ship including the same.
