Mac Tonight was McDonald’s moon-like mascot associated with nighttime advertising in the 1980s.
The character was introduced in 1986 for a campaign promoting McDonald’s evening business. Mac Tonight had a crescent-moon head, wore formal clothing, and sang a version of “Mack the Knife,” giving the advertisements a lounge-style musical identity.
Unlike Ronald McDonald and the McDonaldland characters, Mac Tonight was built around a time-of-day message. His branding encouraged customers to think of McDonald’s as an evening destination as well as a lunch or daytime restaurant.
Mac Tonight is sometimes confused with McDonald’s earlier fictional characters because he appeared in the company’s wider advertising universe. However, he was a distinct 1980s campaign mascot with a moon-shaped design and a specific nighttime positioning.
