Mac Tonight was McDonald's moon-faced character who promoted late-night coffee in 1980s advertising.
McDonald's introduced Mac Tonight in 1986 as part of a campaign aimed at promoting evening restaurant visits. The character had a crescent-moon head, wore sunglasses, and sang a version of “Mack the Knife,” creating a distinct identity from the McDonaldland cast.
The campaign was particularly associated with coffee and nighttime dining. Mac Tonight therefore represented a different branding direction from Ronald McDonald and the child-focused fantasy characters.
Mac Tonight is sometimes confused with a generic moon mascot or with a McDonaldland character. He was a specific McDonald's advertising figure created for a late-1980s campaign, and his name was a pun on the phrase “Mac tonight.”
