Disclosed is a fuel supply system for a liquefied gas carrier. The present invention is to provide a fuel supply system for a liquefied gas carrier, capable of stably supplying fuel to correspond to a change in a generation rate of evaporation gas in a storage tank. According to an embodiment of the present invention, the fuel supply system for a liquefied gas carrier includes: a storage tank storing liquefied gas; an auxiliary tank receiving the liquefied gas from the storage tank and storing the same, wherein the auxiliary tank includes a pressure control unit controlling inner pressure by evaporating a part of the stored liquefied gas; a first fuel supply line compressing the evaporation gas in the storage tank in a compressor and supplying the evaporation gas to a first engine; a second fuel supply line treating the liquefied gas in the auxiliary tank and supplying the treated liquefied gas to the first engine; and a first reliquefaction line heat-exchanging the evaporation gas in the lower part of the compressor in the first fuel supply line with the evaporation gas in the upper part of the compressor and supplying the heat-exchanged evaporation gas to the auxiliary tank.
