The invention discloses a propeller fastening structure and a ship, and belongs to the technical field of ships. The propeller fastening structure comprises a tail shaft which is sequentially provided with a first matching part and a second matching part; the second matching part is sleeved with a propeller and a fastener which is in threaded connection with the first matching part and can fasten the propeller to the second matching part; the fastener is movably connected with at least one braking structure which can rotate along with the fastener and can be clamped with or separated from the tail shaft, so that after the fastener fastens the propeller, the braking structure is clamped with the tail shaft to enable the fastener to be static. The propeller fastening structure provided by the invention has the advantage that the propeller can be reliably fastened to the tail shaft, dismounting and mounting are convenient, time and labor are saved, and the maintenance cost is low.
