What was McDonald’s moon-faced mascot called in its 1980s advertising?

McDonald’s moon-faced mascot in its 1980s advertising was called Mac Tonight.

Mac Tonight debuted in 1986 as part of a campaign aimed at increasing McDonald’s evening business. The character had a crescent-moon head, wore sunglasses and formal evening clothing, and sang a rewritten version of “Mack the Knife” with the hook “It’s Mac Tonight.” The unusual design made the campaign visually distinct from Ronald McDonald and McDonaldland.

Mac Tonight is often remembered as a permanent McDonald’s character, but the campaign was primarily a time-specific promotional effort focused on dinner and late-night visits. The character became particularly associated with McDonald’s advertising in the United States during the latter half of the 1980s. Its moon design also explains why people sometimes confuse the mascot’s name with an informal description such as “Moon Mac.”
