What was the name of McDonald’s talking moon character used in the 1980s?

Mac Tonight was McDonald’s talking moon character used in advertising beginning in 1986.

The character was a crescent moon with a human-like face, dark sunglasses, and a tuxedo. Mac Tonight promoted McDonald’s evening business and was paired with a campaign built around a rewritten version of the song “Mack the Knife.” The character’s relaxed lounge-singer image gave McDonald’s nighttime advertising a distinctive identity.

The campaign began in the United States in 1986 and became especially associated with the phrase “It’s Mac Tonight.” Mac Tonight appeared in television commercials, print material, and restaurant promotions during the period.

Mac Tonight is often confused with ordinary references to McDonald’s late-night dining or with the company’s other mascots. The name belongs specifically to the crescent-moon character, not to a general slogan for nighttime service.
