Steven Dietz (born June 23, 1958) is an American playwright, theatre director, and teacher. Called "the most ubiquitous American playwright whose name you may never have heard", Dietz has long been one of America's most prolific and widely produced playwrights. In 2019, Dietz was again named one of the 20 most-produced playwrights in America. Productions of two new adaptations are scheduled for the 2022-2023 season: "Gaslight" (the first authorized stage adaptation of the Patrick Hamilton thriller, "Gas Light") and "Murder on the Links" (from the novel by Agatha Christie).
