A liquefied gas carrier includes: a tank storing a liquefied gas; a gas fueled engine, to which a boil off gas is supplied as a fuel, the boil off gas being generated when the liquefied gas vaporizes in the tank; a gas supply line, through which the boil off gas is supplied from the tank to the gas fueled engine; a gas compressor disposed on the gas supply line and configured to pressure-feed the boil off gas to the gas fueled engine; a gas return line, through which an excess gas that has not been supplied through the gas supply line to the gas fueled engine is returned to the tank; and a gas return valve configured to open and close the gas return line. The gas return line includes an excess gas spouting portion positioned in a central region of the tank in a height direction and configured to spout the excess gas to the tank.
