The Wizard of Id is a daily newspaper comic strip created by American cartoonists Brant Parker and Johnny Hart. Beginning November 16, 1964, the strip follows the antics of a large cast of characters in a shabby medieval kingdom called "Id". The title is a play on The Wizard of Oz, combined with the Freudian psychological term id, which represents the instinctive and primal part of the human psyche.

John Lewis Hart was an American cartoonist noted as the creator of the comic strips B.C. and The Wizard of Id. Brant Parker co-produced and illustrated The Wizard of Id. Hart was recognized with several awards, including the Swedish Adamson Award and five from the National Cartoonists Society. In his later years, he was known for incorporating Christian themes and messages into his strips. Hart was referred to by Chuck Colson in a Breakpoint column as "the most widely read Christian of our time," over C. S. Lewis, Frank E. Peretti, and Billy Graham.
