The present invention relates to a fuel supply system for a liquefied gas-fueled vessel. According to an embodiment of the present invention, the fuel supply system for a liquefied gas-fueled vessel can comprise: a fuel tank which stores liquefied gas; a liquefied gas supply line which pressurizes and heats the liquefied gas, which is received from the fuel tank, and supplies the liquefied gas to a first combustion engine; a heater installed on the liquefied gas supply line to heat the liquefied gas; an evaporated gas supply line which supplies the evaporated gas, which is generated by evaporating the liquefied gas inside the fuel tank, to a second combustion engine; a liquefied gas pressure-reducing line which is branched from the liquefied gas supply line, and which includes a first pressure-reducing valve installed to reduce the pressure of the liquefied gas which has passed through the heater; a gas-liquid separator which is connected to the liquefied gas pressure-reducing line to separate into a liquid gas and a gaseous gas; an evaporated gas branch line which is branched from the evaporated gas supply line to join the liquefied gas pressure-reducing line; a compressor which is installed on the evaporated gas branch line; and a cooler installed on the evaporated gas branch line on the rear end of the compressor. The present invention aims to provide a fuel supply system for a liquefied gas-fueled vessel, which is able to reliquefy evaporated gas with a simple composition of apparatus without a separate reliquefaction apparatus.
