Mac Tonight was the name of McDonald’s crescent-moon mascot used in late-1980s advertising.
Mac Tonight appeared as a character with a crescent-moon head, dark sunglasses, and a tuxedo. McDonald’s used him in a campaign promoting its evening menu and extended operating hours. The commercials featured a jazz-influenced presentation and a version of the song “Mack the Knife,” giving the campaign a distinct musical identity.
The mascot was introduced in 1986 and became particularly associated with nighttime dining. His visual design was unlike the colorful residents of McDonaldland, showing how McDonald’s sometimes created campaigns aimed at a specific occasion rather than building its central character world.
Mac Tonight is often confused with later moon-themed promotional imagery or with Ronald McDonald. He was a separate advertising character, recognizable by his crescent face and formal eveningwear.
