According to the present invention, disclosed is a fuel gas supply system capable of improving re-liquefaction efficiency of evaporated gas. According to one embodiment of the present invention, the fuel gas supply system comprises: a storage tank to store liquefied gas and evaporated gas; an evaporated gas supply line including a compressing unit to compress the evaporated gas of the storage tank; a nitrogen separator to separate the evaporated gas compressed by passing the compressing unit into a first gas flow containing a nitrogen component of a first concentration and a second gas flow containing a nitrogen component of a second concentration; a first fuel gas supply line to supply the first gas flow to a first engine; a re-liquefaction line to re-liquefy the second gas flow; and a heating amount adjustment unit to measure and adjust a heating amount of the fuel gas supplied to the first engine. The heating amount adjustment unit comprises: a heating amount measurer to measure the heating amount of the fuel gas supplied to the first engine; and a heating amount raising line to directly supply the evaporated gas compressed by passing the compressing unit to the first fuel gas supply line.
