Disclosed is a boil-off gas treatment system of a liquefied hydrogen storage tank for a ship which can efficiently use and store boil-off gas. According to the present invention, the boil-off gas treatment system of a liquefied hydrogen storage tank for a ship comprises: a liquefied hydrogen storage tank to store liquefied hydrogen therein; an LNG storage tank to store LNG therein; and a boil-off gas treatment apparatus to treat liquefied hydrogen boil-off gas created in the liquefied hydrogen storage tank and LNG boil-off gas created in the LNG storage tank. The boil-off gas treatment apparatus includes: a heat exchanger to receive the liquefied hydrogen boil-off gas and the LNG boil-off gas to exchange heat therebetween; and a hydrogen occlusion tank which is filled with a hydrogen occlusion alloy and receives the liquefied hydrogen boil-off gas passing through the heat exchanger to store the liquefied hydrogen boil-off gas. The liquefied hydrogen storage tank is a spherical or a cylindrical storage tank. The heat exchanger and the hydrogen occlusion tank are arranged in an empty space formed between the liquefied hydrogen storage tank and the floor surface of a hull.
