Mac Tonight was the moonwalking character in McDonald’s 1986 advertising campaign.
The character appeared as a person with a crescent-moon head, dark sunglasses, and a tuxedo. His commercials used a modified version of “Mack the Knife,” creating a distinctive musical identity aimed at promoting McDonald’s evening business.
Mac Tonight was not one of the original McDonaldland characters. He was a separate advertising creation associated with nighttime dining and a specific campaign period.
The campaign became especially recognizable because of its combination of the moon image, formal clothing, and dance performance. Mac Tonight is therefore often remembered as a character, but his primary purpose was branding McDonald’s after dark.
