The present invention relates to a liquefied gas storage tank and a vessel including the same. The liquefied gas storage tank of the present invention consists of a first barrier, a first insulation wall, a second barrier, and a second insulation wall and stores extremely low-temperature materials. The first insulation wall may include a connection insulation wall provided in the space between neighboring fixed insulation walls in a state that unit elements formed by stacking the second insulation wall, the secondary barrier, and a fixed insulation wall, a part of the first insulation wall, are neighbored and so disposed. The liquefied gas storage tank may include: a first stepped part which is formed on side surfaces forward and backward and left and right of the connection insulation wall; a second stepped part which is formed on side surfaces forward and backward and left and right of the fixed insulation wall; a first slit which is formed between the connection insulation wall and the fixed insulation wall by the first stepped part and the second stepped part when inserting and installing the connection insulation wall between neighboring fixed insulation walls; and a first charging insulator which charges the first slit.
