Disclosed are a system and a method for reliquefying boil-off gas of a ship, which can increase re-liquefaction performance by effectively cooling boil-off gas to be re-liquefied while controlling boil-off gas temperature within an appropriate range required by a compressor. According to the present invention, the system for reliquefying boil-off gas of a ship comprises: a compressor for compressing boil-off gas generated from liquefied gas stored in a storage tank provided on the ship; a heat exchanger cooling the compressed gas compressed by the compressor; a refrigerant circulation line through which refrigerant supplied to the heat exchanger circulates; a temperature elevating line connected from the storage tank to the compressor; and a heater provided on the temperature elevating line. The heater heats the boil-off gas to an appropriate input temperature of the compressor.
