Disclosed is a fuel gas supply system for ships that can reduce the amount of boil off gas (BOG) to be reliquefied and improve the efficiency of BOG reliquefaction and fuel supply together. According to an embodiment of the present invention, a fuel gas supply system for ships comprises: a compression unit for receiving and compressing BOG from a storage tank for storing BOG of liquefied gas and liquefied gas; a heat exchange unit for liquefying the compressed BOG by heat exchange with a refrigerant; a reliquefaction line connecting the storage tank, the compression unit, and the heat exchange unit; a liquefied gas supply line for supplying the liquefied gas supplied from the storage tank to a customer; and a merging line branched from between the compression unit and the heat exchange unit of the reliquefaction line and connected to the liquefied gas supply line, and joining some of the BOG compressed by the compression unit into the liquefied gas supply line.
