Patrick Lyon (1769, Edinburgh, Scotland – April 15, 1829, Philadelphia, Pennsylvania) was a Scottish-born American blacksmith, mechanic and inventor. After being falsely accused and imprisoned for a 1798 bank robbery, he became a working class hero. A self-made businessman, he was among the foremost American makers of hand-pumped fire engines. Artist John Neagle's portrait of him, Pat Lyon at the Forge (1826–27), alludes to his unjust imprisonment, and is an iconic work in American art.
