Disclosed is an ammonia gas reliquefaction system for a ship that can effectively reliquefy ammonia boil-off gas generated in a fuel tank and return it to the fuel tank. According to an embodiment of the present invention, the ammonia gas reliquefaction system for a ship comprises: an absorption tower which produces ammonia water by reacting water with ammonia gas used as a refrigerant; a distillation tower which receives ammonia water from the absorption tower and separates it into water and ammonia gas; and a reliquefaction unit which receives the separated ammonia gas and uses it as a refrigerant, cools the refrigerant using liquid ammonia supplied from a fuel tank, and reliquefies the ammonia gas discharged from the fuel tank through heat exchange with the refrigerant.
