The present invention is to provide a liquefied cargo storage tank and a ship that can reduce manufacturing costs while safely storing liquefied cargo by manufacturing it as an atmospheric cylindrical tank with a vapor pressure of 0.7 bar(g) or less, rather than a pressurized cylindrical tank with a vapor pressure of 2.0 bar(g) or more. The present invention relates to a liquefied cargo storage tank comprising: a tank shell having a cylindrical shape and forming a space for storing liquefied cargo; an insulating unit formed to surround the tank shell; first and second saddle units for supporting and fixing one side and the other side of the tank shell; an annular space formed between the tank shell and the insulating unit and divided into first, second, and third spaces by the first and second saddle units; and a leak protection device for collecting and storing the liquefied cargo leaking into at least one among the first, second, and third spaces.
