Ronald J. Watkins is an American nonfiction writer, editor, and collaborator known for investigative works and historical narratives.

As an author, he has written several notable books, including High Crimes and Misdemeanors, an account of the impeachment of Arizona governor Evan Mecham, and Birthright, about the Shoen family and the murder of Eva Shoen.
