The North River Steamboat or North River, colloquially known as the Clermont, is widely regarded as the world's first vessel to demonstrate the viability of using steam propulsion for commercial water transportation. Built in 1807, the North River Steamboat operated on the Hudson River – at that time often known as the North River – between New York City and Albany, New York. She was built by the wealthy investor and politician Robert Livingston and inventor and entrepreneur Robert Fulton (1765–1815).
