An ammonia gas re-liquefaction system of a ship is disclosed. The ammonia gas re-liquefaction system of a ship according to an embodiment of the present invention comprises: an absorption tower that receives ammonia gas used as a refrigerant and reacts the ammonia gas with water to generate ammonia water; a distillation tower that receives ammonia water from the absorption tower and separates the ammonia water into water and ammonia gas; and a re-liquefaction part that re-liquefies the ammonia gas supplied from a fuel tank using the ammonia gas discharged from the distillation tower as a refrigerant, wherein the refrigerant is circulated and supplied to the absorption tower, distillation tower, and re-liquefaction part. Thus, the present invention can provide the ammonia gas re-liquefaction system of a ship that can effectively re-liquefy ammonia boil-off gas generated in the fuel tank and return the same to the fuel tank.
