The present invention provides a pre-swirl stator, which is installed at the front of a propeller of a stern. The pre-swirl stator includes: a first stator, a second stator, and a third stator provided on a port side of a ship; and a fourth stator provided on a starboard side, wherein the first stator, the second stator, and the third stator are sequentially installed to be spaced apart from each other in directions of a bow side and a bottom side to be arranged on a side surface of the stern in a diagonal direction. Therefore, the pre-swirl stator can improve the propulsion efficiency of the ship.
