What was the name of McDonald's moon-headed character introduced in 1986?

McDonald's introduced the moon-headed advertising character Mac Tonight in 1986.

Mac Tonight appeared as a smiling crescent moon wearing sunglasses and singing a rewritten version of “Mack the Knife.” The campaign targeted adults and promoted McDonald's evening hours, giving the brand a musical and visually unusual identity beyond its family-focused characters.

The character was especially associated with actor Doug Jones in the original television advertisements, although the campaign's most memorable feature was the moon-shaped head and lounge-singer presentation.

Mac Tonight is sometimes confused with Ronald McDonald or the McDonaldland cast. He was a separate advertising character created for a specific nighttime campaign, rather than one of the long-running central mascots.
