Disclosed herein is an exhaust gas waste heat recovery system for ships. The exhaust gas waste heat recovery system includes: a heat-transfer medium circulation line provided to a ship and allowing a working fluid to circulate therealong; a vaporizer provided to the heat-transfer medium circulation line and vaporizing the working fluid through heat exchange with an exhaust gas discharged from an engine of the ship; and an expansion turbine provided to the heat-transfer medium circulation line, receiving the working fluid, and generating shaft power while expanding the received working fluid, wherein the engine is fueled by a low-flashpoint liquefied gas, and the working fluid undergoes phase change from liquid to gas using the exhaust gas from the engine fueled by the low-flashpoint liquefied gas as a heat source while circulating in a closed loop along the heat-transfer medium circulation line.
