An ammonia fuel supply device is provided by an embodiment of the present invention. The ammonia fuel supply device according to an embodiment of the present invention comprises: a storage tank for storing liquid ammonia; a fuel supply pipe for supplying liquid ammonia from the storage tank to a combustion engine; a boosting pump connected to the fuel supply pipe to increase the supply pressure of the liquid ammonia supplied from the storage tank; a BOG discharge pipe that is connected to the storage tank to discharge ammonia generated by natural vaporization of liquid ammonia; and a compressor connected to the BOG discharge pipe to compress ammonia to the pressure required by the combustion engine, wherein the BOG discharge pipe at the rear end of the compressor may be connected to the fuel supply pipe at the rear end of the boosting pump, thereby capable of effectively preventing the tank pressure rise.
