George Walter McCoy (1876–1952) was an American physician. An international expert on leprosy, he served as director of the National Institute of Health for more than twenty years.

McCoy was born in 1876 in the Cumberland Valley of Pennsylvania.^[1] He was the son of Osborn George McCoy and his wife Lavanda Walters, and had one sibling, J. Ross McCoy, who died young in 1899.^[2] He graduated from the University of Pennsylvania School of Medicine in 1898 and completed his internship at City Hospital in Newark, New Jersey.^[3]

After completing his internship, McCoy joined the United States Public Health Service and was assigned to the U.S. Marine Hospital in San Francisco, California.^[4] While stationed in San Francisco, he became the director of the U.S. Plague Laboratory in 1908,^[3] and during his time there he discovered, and later isolated the pathogen responsible for, a "plague-like disease of rodents", later dubbed tularemia.^[5] In 1911, he was transferred to direct the U.S. Leprosy Investigation Station in Hawaii.^[3] In 1915, he was appointed the fourth head of the U.S. Hygienic Laboratory, which was renamed the National Institute of Health in 1930.^[4]

McCoy directed the NIH for more than twenty years, during which the agency expanded significantly. Apart from his administrative role, he continued to conduct major medical studies on a variety of diseases, and advocated a combined field and laboratory approach to public health research.^[1] He resigned his position as director in early 1937, but remained with the Public Health Service to conduct a large, nationwide survey on leprosy.^[4] In 1938, he left the PHS and joined the staff of the Louisiana State University School of Medicine in New Orleans, where he headed the Department of Preventive Medicine and Public Health until his retirement in 1948.^[3] He died on 2 April 1952.^[1]

McCoy served as president of the American Association of Immunologists from 1922-3. He was made an honorary member of Delta Omega in 1930.^[6] He was awarded the American Public Health Association's Sedgwick Memorial Medal in 1931.^[7]
