The Tuskegee Study of Untreated Syphilis in the Negro Male, also known as the Tuskegee Syphilis Study or Tuskegee Syphilis Experiment was an infamous clinical study conducted between 1932 and 1972 by the U.S. Public Health Service.

The Public Health Service started working on this study in 1932, in collaboration with Tuskegee University, a historically black college in Alabama. Investigators enrolled in the study a total of 600 impoverished, African American sharecroppers from Macon County, Alabama.
