James Rumsey (1743 – December 21, 1792) was an American mechanical engineer chiefly known for exhibiting a boat propelled by machinery in 1787 on the Potomac River at Shepherdstown in present-day West Virginia before a crowd of local notables, including Horatio Gates. A pump driven by steam power ejected a stream of water from the stern of the boat and thereby propelled the boat forward.
