According to an embodiment of the present invention, provided is an ammonia fuel supply apparatus capable of easily generating urea water even when a ship sails in a polar region and supplying ammonia according to the state of ammonia required for each of a combustion engine and a selective catalytic reduction reactor. An ammonia fuel supply apparatus according to an embodiment of the present invention may comprise: a urea tank for storing solid urea; a pure water supply pipe connected to a pure water storage tank for storing pure water, to supply the pure water; a heater unit for heating the pure water by heat exchanging with an exhaust gas discharged from a combustion engine; a urea water generation unit including a urea water generation tank for generating urea water by mixing the solid urea with the pure water; a heating unit for generating a mixed gas including ammonia by heat exchanging the urea water supplied from the urea water generation unit with the exhaust gas; and a separation unit for generating liquid ammonia from which water and carbon dioxide are removed by cooling to room temperature and pressurizing the mixed gas supplied from the heating unit, and separating the liquid ammonia and then supplying the liquid ammonia to the combustion engine.
