Disclosed is a fuel gas supply system. According to an embodiment of the present invention, a fuel gas supply system includes: a storage tank storing liquefied gas and evaporative gas; an evaporative gas supply line including a compression part pressurizing the evaporative gas of the storage tank; a nitrogen separator separating the evaporative gas, pressurized through the compression part, 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 supplying the first gas flow to a first engine; and a re-liquefying part receiving and re-liquefying the second gas flow. Therefore, the present invention is capable of improving the performance and efficiency of the re-liquefaction of the evaporative gas.
