Lewis Morris Rutherfurd (November 25, 1816 – May 30, 1892) was an American lawyer and astronomer, and a pioneering astrophotographer.

Lewis Rutherfurd abandoned his study of law in 1849 to dedicate his leisure to science, particularly astronomy. He performed pioneering work in spectral analysis, and experimented with celestial photography. He invented instruments for his studies, including the micrometer for measuring photographs, a machine for producing improved ruled diffraction gratings, and the first telescope designed specifically for astrophotography.

Using his instrumentation, Rutherfurd produced a quality collection of photographs of the Sun, Moon, and planets, as well as star clusters and stars down to the fifth magnitude. In 1862 he began making spectroscopic studies using his new diffraction grating. He noticed distinct categories of spectral classes of stars, which Angelo Secchi expanded upon in 1867 to list a set of four stellar classes.
