A propulsion device for a marine vessel that is able to improve the power efficiency of an electric motor is provided. The propulsion device for the marine vessel that propels the marine vessel, includes a driving source including at least one electric motor, a propeller that includes a plurality of blades whose pitches are changeable and rotates around a central axis of a propeller shaft together with the propeller shaft, a propeller shaft rotation drive unit that transmits a driving force from the driving source to the propeller shaft and rotates the propeller shaft around the central axis, and a pitch change drive unit that transmits the driving force from the driving source to the respective blades and changes pitches of the respective blades. The propeller shaft rotation drive unit includes a first shaft. The pitch change drive unit includes a second shaft disposed closer to a bow side of the marine vessel than the first shaft.
