Provided is an ammonia fuel vessel according to one embodiment of the present invention, which may increase space availability in a ship. The ammonia fuel vessel according to one embodiment of the present invention may comprise: a ship body; a fuel tank which is installed in a ship body and stores liquid ammonia; a boiler which receives the liquid ammonia or ammonia generated by evaporating the liquid ammonia from a first fuel supply pipe connected to the fuel tank and performs combustion to generate steam; a first post-processing device which is installed on a first exhaust pipe connected to the boiler and reduces at least one of nitrous oxide or nitrogen oxide included in exhaust gas generated from the boiler; a first reducing agent supply pipe which connects the fuel tank and the first post-processing device and supplies the liquid ammonia or ammonia inside the fuel tank to the first post-processing device as a reducing agent; an engine which receives the liquid ammonia or ammonia from a second fuel supply pipe connected to the fuel tank and performs combustion; and a recovery pipe which recovers the liquid ammonia or ammonia remaining inside the first reducing agent supply pipe and supplies the liquid ammonia or ammonia to the engine or boiler.
