The Librarianist is a 2023 novel by Canadian-born author Patrick deWitt.

It follows a retired librarian named Bob Comet and is billed as a "wide-ranging and ambitious document of the introvert's condition.

"[4] Sam Sacks of The Wall Street Journal called it "Mr. deWitt's smoothest book by far, one more prone than usual to clichés [...] but also more warmhearted.

It shares the attributes of its hero: likable, unshowy, somewhat dull but reliably soothing.

"[5] It was the winner of the 2024 Stephen Leacock Memorial Medal for Humour.
