William Augustus Hinton (15 December 1883, Chicago, Illinois – 08 August 1959, Canton, Massachusetts) was an American bacteriologist, pathologist and educator.
He was the first black professor in the history of Harvard University.
A pioneer in the field of public health, Hinton developed a test for syphilis which, because of its accuracy, was used by the United States Public Health Service.
In 2019, Hinton's portrait was placed in Harvard Medical School's Waterhouse Room, a room previously dominated by the portraits of former Harvard Medical School Deans, all of whom are white.
