A fuel gas supply system for a ship is disclosed. In accordance with an embodiment of the present invention, the fuel gas supply system for a ship comprises: a compression unit for receiving boil-off gas of liquefied gas from a storage tank for storing the liquefied gas and the boil-off gas, and compressing the same; a heat exchange unit for exchanging the heat between the compressed boil-off gas and a refrigerant and liquefying the same; a reliquefaction line for connecting the storage tank, the compression unit, and the heat exchange unit; a liquefied gas supply line for supplying the liquefied gas, received from the storage tank, to a customer; a mixer provided in the liquefied gas supply line, and storing the liquefied gas received from the storage tank; a merging line branched from the space between the compression unit and the heat exchange unit in the reliquefaction line, connected to the mixer, and for supplying a portion of the boil-off gas, compressed by the compression unit, to the mixer; and a re-supply line for connecting the mixer and a front end of the heat exchange unit in the reliquefaction line, and supplying a gas component, generated in the mixer, to the front end of the heat exchange unit in the reliquefaction line so that the gas component is mixed with the boil-off gas compressed by the compression unit and introduced into the heat exchange unit. Therefore, the amount of boil-off gas to be reliquefied can be reduced.
