What was the name of McDonald’s crescent-moon-headed advertising character?

Mac Tonight was McDonald’s crescent-moon-headed advertising character.

McDonald’s introduced Mac Tonight in 1986 as the central figure in a campaign promoting evening dining. The character had a crescent moon for a head, wore formal clothing, and sang a rewritten version of the song “Mack the Knife,” helping give the campaign a distinctive musical and visual identity.

Mac Tonight was separate from the earlier McDonaldland cast. He was created for a specific advertising campaign rather than as a permanent resident of that fictional world. The character became especially associated with nighttime restaurant visits and McDonald’s extended evening hours.

The character is sometimes confused with brand mascots such as Ronald McDonald or Speedee. Those figures represented broader company or product identities, whereas Mac Tonight was tied closely to a late-1980s advertising concept.
