The invention provides a ship stern structure which comprises a water diversion heel and a steel casting, the water diversion heel comprises a head end connecting part and a tail end connecting part, and the head end connecting part is connected with a ship body outer plate. The steel casting comprises a head end face and a tail end face, the two end faces and the ship body tail shaft are arranged in a concentric circle mode, the middle longitudinal position of the bottom of the steel casting downwards protrudes out of a ship body outer plate by a preset distance to form a connecting unit, and the connecting unit is in transition connection with the tail end face of the steel casting through a first arc. The connecting unit is in transition connection with the water diversion heel through a second arc, an included angle is formed between the connecting unit and the normal direction of the hull outer plate, the included angle is consistent with the groove angle of the butt joint position of the hull outer plate, and the tail end connecting part of the water diversion heel is connected with the steel casting through the connecting unit. And the tail end surface of the steel casting exceeds the end surface of the tail end connecting part of the water diversion heel. The connection transition problem of the water diversion heel structure, the tail shaft shell steel casting and the ship body structure is solved.
