Disclosed is a fuel gas supply system. According to one embodiment of the present invention, the fuel gas supply system comprises: a first fuel gas supply line provided with a storage tank which receives a liquefied gas and a vaporization gas and a compression part which pressurizes the vaporization gas of the storage tank and supplies the vaporization gas pressurized by passing through the compression part to a first engine; a second fuel gas supply line supplying to a second engine the vaporization gas branched in the middle part of the compression part and partially pressurized by the compression part; a reliquefaction line supplied with a part of the pressurized vaporization gas to reliquefy; and a heating value control element which measures and controls a heating value of the fuel gas supplied to the second engine, wherein the reliquefaction line includes a cooling part which cools the pressurized vaporization gas, a first expansion valve which primarily decompresses the pressurized vaporization gas passing through the cooling part, a first gas-liquid separating unit which separates the vaporization gas in a gas-liquid mixture state passing through the first expansion valve into a gas component and a liquid component, and a vaporization circulation line which supplies to the second engine the gas component separated in the first gas-liquid separating unit, and a liquefied circulation line supplied with the liquid component separated in the first gas-liquid separating unit.
