Henry Roe Campbell (September 9, 1807 – February 6, 1879) was an American surveyor and civil engineer. Campbell contributed to American railroading and bridge-building in the first half of the 19th century. Campbell patented his 4-4-0 design in February 1836, just a few months before the patent law was changed to require that claims include proof of originality or novelty.
