B.C. is a daily American comic strip created by cartoonist Johnny Hart. Set in prehistoric times, it features a group of cavemen and anthropomorphic animals from various geologic eras.

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.
