According to the present invention, a ship having a fluctuation pressure reduction device comprises: a pressure absorbing unit; and a pressure adjustment unit configured to adjust internal pressure of a pressure chamber. The pressure absorbing unit comprises: the pressure chamber, of which one surface is opened, provided in a stern; a mass member installed to be moved inside the pressure chamber by the fluctuation pressure due to rotation of a propeller; a cover member installed on one opened surface of the pressure chamber and having one or more holes connected with the outside; and a buffer member disposed between the mass member and the cover member to block an impact of the mass member and the cover member and block flow of sea water toward the inside of the pressure chamber.
