The present invention relates to a reliquefaction system of evaporation gas and a ship, comprising: a liquefied gas storage tank; an evaporation gas compressor for compressing evaporation gas generated from the liquefied gas storage tank; a liquefaction portion for liquefying the evaporation gas by using mixed refrigerant; a gas combustor for combusting the evaporation gas; an evaporation gas liquefaction line connected from the liquefied gas storage tank to the liquefaction portion and provided with the evaporation gas compressor; a free-flow line connected from the liquefied gas storage tank to the gas combustor; and an evaporation gas transferring line divided from the free-flow line and connected to the evaporation gas liquefaction line between the evaporation gas compressor and the liquefaction portion. An object of the present invention is to improve liquefaction efficiency in the evaporation gas reliquefaction process.
