Harvey Bialy was an American molecular biologist and AIDS denialist. He was one of the signatories to a letter to the editor by the "Group for the Scientific Reappraisal of the HIV-AIDS Hypothesis", which denied that HIV was the cause of AIDS, and was a member of the controversial and heavily criticized South African Presidential AIDS Advisory Panel convened by Thabo Mbeki in 2000. Bialy authored a scientific biography of Peter Duesberg, a fellow AIDS denialist, in 2004.
