Paul Drummond Cameron (born November 9, 1939) is an American psychologist.
Cameron has been designated by the Southern Poverty Law Center as an anti-gay extremist.
While employed at various institutions, including the University of Nebraska, he conducted research on passive smoking, but he is best known today for his claims about homosexuality.
After a successful 1982 campaign against a gay rights proposal in Lincoln, Nebraska, he established the Institute for the Scientific Investigation of Sexuality (ISIS), now known as the Family Research Institute (FRI).
As FRI's chairman, Cameron has written contentious papers asserting associations between homosexuality and the perpetration of child sexual abuse and reduced life expectancy.
These have been heavily criticized by others in the field.

In 1983, the American Psychological Association expelled Cameron for non-cooperation with an ethics investigation.
Position statements issued by the American Sociological Association, Canadian Psychological Association, and the Nebraska Psychological Association accuse Cameron of misrepresenting social science research.
