Provided is a fuel supply system for a ship. According to the present invention, the fuel supply system for a ship comprises: a fuel supply line arranged in the ship, and connected from an ammonia storage tank storing ammonia to an engine in the ship; a compression unit arranged in the fuel supply line and compressing ammonia with a pressure needed for the engine; a fuel recollection line recollecting the ammonia discharged from the engine; an exhaust gas discharge line discharging the exhaust gas generated in the engine to the outside of the ship; and a selective catalytic reduction unit arranged in the exhaust gas discharge line and denitriding the exhaust gas. The ammonia is supplied as a reducing agent for the selective catalytic reduction unit from the ammonia storage tank or the fuel supply line. Therefore, time and space required for installation can be reduced.
