The present invention relates to a liquefied gas storage tank and a ship including the same. The present invention includes: a wall including a primary barrier made of metal that forms a storage space for containing liquefied gas, a primary insulation wall provided outside the primary barrier, a secondary barrier provided outside the primary insulation wall, and a secondary insulation wall provided outside the secondary barrier, and independently forming first and second insulated spaces between the primary barrier and the secondary barrier and outside the secondary barrier, respectively; a dome provided on the upper surface of the storage space and penetrating the wall to connect the storage space to the outside; and an insulated space passage part provided in the wall at a point spaced apart from the dome and penetrating the secondary barrier to connect the primary insulated space to the outside. Accordingly, the sealing properties and structural stability of the dome can be secured.
