"The Kekulé Problem" is a 2017 essay written by the American author Cormac McCarthy for the Santa Fe Institute (SFI). It was McCarthy's first published work of non-fiction. The science magazine Nautilus first ran the article online on April 20, 2017, then printed it as the cover story for an issue on the subject of consciousness. David Krakauer, an American evolutionary biologist who had known McCarthy for two decades, wrote a brief introduction. Don Kilpatrick III provided illustrations.
