The Hudson–Fulton Celebration from September 25 to October 9, 1909 in New York and New Jersey was an elaborate commemoration of the 300th anniversary of Henry Hudson’s discovery of the Hudson River and the 100th anniversary of Robert Fulton's first successful commercial application of the paddle steamer. The maritime achievements of Hudson and Fulton foreshadowed the importance of the river to New York's progress and identity. Organizers used the event not only to display the success of the two men, but also the status of New York City as a world city and the achievements of its citizens.
