Amasa Holcomb (1787–1875) was an American farmer, surveyor, civil engineer, businessman, politician, and manufacturer of surveying instruments and telescopes. From instruments he made he observed the total solar eclipse of June 16, 1806. He made astronomical computations from his observations and published almanacs for the partial solar eclipses of 1807 and 1808 from his work. An asteroid, 45512 Holcomb, was named after him.
