The present invention provides a device for supplying an ammonia fuel. The device for supplying an ammonia fuel can improve space occupancy in a vessel and effectively reduce nitrogen oxide caused by combustion of an ammonia fuel. According to an embodiment of the present invention, the device for supplying an ammonia fuel includes: a urea storage tank storing solid urea and supplying the ammonia fuel to a combustion engine by being installed in the vessel; a urea solution generating unit receiving the solid urea from the urea storage tank and generating a urea solution; a heating unit heating the urea solution supplied from the urea solution generating unit and generating a mixed gas including ammonia; a cooling unit cooling the mixed gas supplied from the heating unit in order and generating liquid ammonia in which water and carbon dioxide are removed, thereby supplying the liquid ammonia to the combustion engine; and a water circulation pipe enabling the water discharged from the cooling unit to circulate to the urea solution generating unit.
