Disclosed is a fuel supply system for a ship, which can further improve an effect of reducing greenhouse gas emission during an operation of a ship. The fuel supply system for a ship of the present invention includes: a storage tank which stores liquid ammonia in a ship provided with a propulsion engine and a power generation engine; an oil tank which stores oil to be supplied as fuel in the ship; an ammonia supply line which supplies the liquid ammonia of the storage tank to the power generation engine; a selective catalytic reduction unit which denitrifies exhaust gas generated in the propulsion engine and the power generation engine; a reductant supply line which supplies the liquid ammonia of the storage tank to the selective catalytic reduction unit; and an air lubrication system which injects air onto an outer bottom surface of the ship to decrease frictional resistance when the ship moves. Electric power produced from the power generation engine is supplied to the air lubrication system.
