According to one embodiment of the present invention, an ammonia fuel supply apparatus is provided. According to one embodiment of the present invention, the ammonia fuel supply apparatus includes: a storage tank storing liquefied ammonia; a first fuel supply pipe supplying the liquefied ammonia from the storage tank to a first combustion engine; a pressure boosting pump connected to the first fuel supply pipe to increase supply pressure of the liquefied ammonia supplied from the storage tank; a temperature control unit connected to the first fuel supply pipe at the rear end of the pressure boosting pump to increase the temperature of the liquefied ammonia supplied to the first combustion engine; a BOG discharge pipe connected with the storage tank to discharge ammonia produced from the natural evaporation of the liquefied ammonia; a compressor connected to the BOG discharge pipe to compress the ammonia; a second fuel supply pipe branched from the compressor to supply the ammonia to a second combustion engine; a heat exchanger connected to the BOG discharge pipe at the rear end of the compressor; and a first fuel transfer pipe having one end connected to the first fuel supply pipe at the front end of the pressure boosting pump, and having the other end connected to the second fuel supply pipe via the heat exchanger, wherein the BOG discharge pipe at the rear end of the heat exchanger can be connected to the storage tank. Therefore, the present invention is capable of increasing the efficiency of the apparatus while preventing a pressure rise in the storage tank.
