Disclosed are an ammonia boil-off gas reliquefaction system and method for a ship. According to the present invention, the ammonia boil-off gas reliquefaction system for a ship comprises: an ammonia storage tank arranged in the ship and storing ammonia to be supplied as fuel for an engine in the ship; a fuel supply line connected from the ammonia storage tank to the engine and supplying ammonia; a heater arranged in the fuel supply line and heating the ammonia to be supplied to the engine by exchanging heat with a heat medium; a compressor receiving boil-off gas generated from the ammonia storage tank and compressing the boil-off gas; and a cooler cooling the boil-off gas compressed in the compressor. The cooler heats the ammonia to be supplied as fuel for the engine in the heater, and cools the boil-off gas by receiving the cooled heat medium. Therefore, reliquefaction efficiency can be increased.
