Barnet Mortimer Levy (January 13, 1917 – March 7, 2014) was an American oral pathologist and professor at universities in the United States and Mexico. Levy worked to integrate basic science research into dentistry, believing that oral health should not be separated from other aspects of health. He co-authored an influential textbook, co-founded a research institute in Texas, and served in national leadership roles, including the presidency of the International Association for Dental Research and the American Academy of Oral & Maxillofacial Pathology.
