A gas reliquefaction system according to the present invention is for liquefying boil-off gas using a mixed refrigerant, comprising: a mixed refrigerant compressor for compressing the mixed refrigerant; a cooler for cooling the mixed refrigerant compressed in the mixed refrigerant compressor; and a re-liquefier for liquefying the boil-off gas by heat exchange with the cooled mixed refrigerant discharged from the cooler. In order to prevent a decrease in the reliquefaction efficiency due to a decrease in the temperature of the mixed refrigerant, the gas reliquefaction system can use the cooling heat of the boil-off gas.
