An ammonia gas reliquefaction system of a ship is disclosed. According to an embodiment of the present invention, an ammonia gas reliquefaction system of a ship comprises: a compression unit which receives boil-off gas from a storage tank storing liquefied ammonia and its boil-off gas and compresses it; a cooling unit which cools the compressed boil-off gas; a gas-liquid separator which separates the cooled fluid from gas and liquid; and a pressure control valve provided in a gas discharge line of the gas-liquid separator and whose opening degree is controlled based on the internal pressure of the gas-liquid separator so that the gas-liquid separator is operated at the set pressure.
