Disclosed is a fuel gas supply system. A fuel gas supply system according to an embodiment of the present invention includes: a storing tank receiving a liquefied gas and an evaporative gas of the liquefied gas; a buffer tank storing the liquefied gas received from the storing tank; a first fuel supply line having a compressing unit compressing the evaporative gas of the storing tank and supplying the evaporative gas compressed by the compression unit to a first engine; a reliquefaction unit receiving and reliquefying at least a supply of some of the compressed evaporative gas or some of the evaporative gas being compressed inside a middle part of the compression unit and supplying the reliquefied evaporative gas to the storing tank; a pressure generating device increasing or maintaining the inner pressure of the buffer tank; and a precooling line injecting the liquefied gas discharged by the pressure generating device to the inside of the storing tank. The purpose of the present invention is to provide the fuel gas supply system capable of efficiently treating or using evaporative gas.
