Disclosed is a fuel gas supply system. A fuel gas supply system according to an embodiment of the present invention includes a storage tank receiving a fuel gas composed of a liquefied gas and an evaporative gas; an evaporative gas supplying line having a compressing unit pressing the evaporative gas received in the storage tank and supplying the evaporative gas penetrated through the compressing unit to an engine; and a re-liquefing line including a pressing unit branched from the evaporative gas supplying line, receiving the evaporative gas compressed by penetrating through the compressing unit, an pressing the received evaporative gas, an oil removing unit removing oil from the evaporative gas pressed by passing through the pressing unit, a heat-exchange device heat-exchanging the evaporative gas penetrated through the oil removing unit and the evaporative gas in a front end of the compressing unit, an expansion valve decreasing a pressure of the evaporative gas penetrated through the heat-exchanging device, and a gas-liquid separating device separating the gaseous components and liquid components from the evaporative gas of which the pressure is decreased by penetrating through the expansion valve. The purpose of the present invention is to provide the fuel gas supplying system capable of effectively processing or using the evaporative gas.
