Disclosed is a waste heat recovery system for a ship to efficiently use reaction heat generated during ammonia synthesis. According to the present invention, the waste heat recovery system for a ship comprises: an ammonia demand source provided on a ship and supplied with ammonia as fuel; a nitrogen generator generating purging nitrogen to be supplied to the inside of the ship; a hydrogen tank provided on the ship and storing liquefied hydrogen; an ammonia generation unit receiving the nitrogen generated from the nitrogen generator and the hydrogen from the hydrogen tank to synthesize ammonia; and a first ammonia supply line supplying the ammonia synthesized in the ammonia generation unit to the ammonia demand source. The ammonia demand source is preheated to an operation temperature by reaction heat generated during ammonia synthesis in the ammonia generation unit.
