A ship exhaust gas waste heat recovery system is disclosed. The ship exhaust gas waste heat recovery system of the present invention comprises: a heat medium circulation line provided on a ship, wherein a working fluid circulates therethrough; a vaporizer provided in the heat medium circulation line and heating the working fluid through heat exchange with exhaust gas discharged from the engine of the ship; a gas-liquid separator provided in the heat medium circulation line and receiving the heated working fluid from the vaporizer to separate gas-liquid; an expansion turbine for receiving the gaseous working fluid separated from the gas-liquid separator and expanding the working fluid to produce axial power; a condenser for receiving the expanded and cooled working fluid that passes through the expansion turbine, cooling the working fluid, and changing the phase of the working fluid into liquid; a supply pump provided in the heat medium circulation line, receiving the working fluid condensed from the condenser, and pressurizing the working fluid; and a liquid line for supplying the liquid working fluid separated in the gas-liquid separator to the rear end of the expansion turbine of the heat medium circulation line. The engine is supplied with low flash point liquefied gas as fuel. Therefore, the energy efficiency of a ship can be improved.
