The present invention relates to a waste heat recovery system for an engine coolant of a ship. According to an embodiment of the present invention, the waste heat recovery system for an engine coolant of a ship, which recovers waste heat generated from an engine of a ship and supplies the waste heat to each source of demand, comprises: a waste heat recovery system unit formed to recover waste heat through heat exchange with an engine coolant; an engine coolant system unit formed to circulate and flow the engine coolant; a heat exchanger installed between the waste heat recovery system unit and the engine coolant system unit, and performing heat exchange to recover the waste heat from the engine coolant flowing along the engine coolant system unit to the waste heat recovery system unit; and a controller for controlling waste heat recovery of the waste heat recovery system unit by comparing the temperature of the engine coolant after heat exchange in the heat exchanger with a preset reference temperature. Accordingly, the waste heat can be more efficiently recovered.
