Duren v. Missouri, 439 U.S. 357 (1979), was a United States Supreme Court case related to the Sixth Amendment.

It challenged Missouri's law allowing gender-based exemption from jury service.

Part of her argument was that making jury duty optional for women should be struck down because it treated women's service on juries as less valuable than men's, and also discriminated against men who enjoyed no such exemption.

He claimed that this Missouri law violated his sixth amendment rights to an impartial jury.

Missouri state law at that time permitted women (and those over age 65) to be exempted from jury duty upon request.
