One embodiment of the present invention provides a fuel supply system for a liquefied gas fueled vessel, capable of saving costs for generating a separate heating source. According to one embodiment of the present invention, the fuel supply system for a liquefied gas fueled vessel comprises: a fuel tank to store liquefied gas; a liquefied gas support line to pressurize, heat, and supply the liquefied gas supplied from the fuel tank to a first combustion engine; a heater install in the liquefied gas supply line to heat the liquefied gas; an evaporated gas supply line to supply a second combustion engine with evaporated gas generated by liquefying the liquefied gas in the fuel tank; a liquefied gas decompression line branched from the liquefied gas supply line and having a first decompression valve to decompress the liquefied gas passing through the heater; a gas-liquid separator connected to the liquefied gas decompress line to separate the liquefied gas into liquid gas and gaseous gas; an evaporated gas branch line branched from the evaporated gas supply line to join in the liquefied gas decompression line; and a compressor installed in the evaporated gas branch line.
