Stuart Arthur Kornfeld (October 4, 1936 – August 17, 2025) was an American professor of medicine at Washington University in St. Louis and researcher in glycobiology.

Kornfeld was born in St. Louis on October 4, 1936, to Ruth and Max Kornfeld. He graduated from Ladue Horton Watkins High School in 1954. He received his A.B. in 1958 from Dartmouth College and his MD in 1962 from Washington University School of Medicine. In 1959, he married Rosalind Hauk, a PhD student at Washington University.

After medical school, Kornfeld did an internship at Barnes Hospital in St. Louis, and spent 2 years (1963–1965) as a research associate at the National Institute of Arthritis and Metabolic Diseases of the National Institutes of Health. He then returned to Washington University where he has remained since, serving as the school's hematology division head for thirty years. He and his wife Rosalind, with whom he collaborated scientifically, were recruited to the faculty in 1966 alongside Phil Majerus by the University's Chairman of Medicine.
