Nathan Smith Davis Sr., M.D., LLD (January 9, 1817 – June 16, 1904) was a physician who was instrumental in the establishment of the American Medical Association and was twice elected its president. He became the first editor of the Journal of the American Medical Association.

Davis was born near Greene, Chenango County, New York. He lived and worked on the farm until 16 years of age, attending district school in the winter, and studying for six months in Cazenovia Seminary. At the age of 17 he began mastering medicine under Dr. Daniel Clark, attended three courses of lectures at the College of Physicians and Surgeons of the Western District of New York, Fairfield, and was graduated from that institution, on January 31, 1837, with a thesis on "Animal Temperature". He first practiced in Vienna, New York, but after a few months moved to Binghamton, New York and soon after settled in New York City.

In 1841, he was awarded the prize from the Medical Society of the State of New York for the best "Analysis of the Discoveries Concerning the Physiology of the Nervous System." About seven years later the State Agricultural Society of New York awarded him a prize for a "Text-Book on Agricultural Chemistry." He became a member of the Broome County Medical Society, and was one of its censors in 1838. In 1841, 1842 and 1843 he was secretary and librarian of the society, and in 1843 delegate from Broome County to the Medical Society of the State of New York. In 1845 his report as chairman of the Committee on Correspondence relative to Medical Education and Examination led to the organization of the American Medical Association.

Almost from the beginning of his career, Davis was identified with medical education. While in Binghamton, he obtained a cadaver and demonstrated anatomy to medical students. His first work as a teacher was lecturer and demonstrator of anatomy in the College of Physicians and Surgeons in the city of New York in 1848. A year later he moved to Chicago and accepted the chair of physiology and pathology in Rush Medical College. A year later, in addition, he assumed the duties of the chair of practice of medicine, and remained connected with the institution for ten years. Soon after he became connected with this college, he appreciated the necessity of a better system of medical education, as at that time there was no classification of students and no adjustable curriculum. He began to agitate for reform, but was opposed. He withdrew, and with a few colleagues founded the Chicago Medical College, of which he was for more than forty years the dean and professor of principles and practice of medicine. When Davis arrived in Chicago, there was no organization of physicians, and he was one of the prime movers in the Chicago Medical Society and the Illinois State Medical Society. For twelve years he was secretary of the Chicago Medical Society, and in 1855 served as its president.
