Speedee was the title of McDonald's first official mascot, introduced in 1948.
Speedee was depicted as a chef-like figure and represented the McDonald brothers' Speedee Service System. That system emphasized quick preparation and service, a central part of the restaurant's early identity after the brothers redesigned their business in 1948.
The mascot appeared in early McDonald's branding before Ronald McDonald became the dominant public character. Speedee was also associated with the restaurant's early signs and advertising, helping communicate the promise of fast service.
Speedee is often confused with later McDonald's characters. Ronald McDonald was introduced in 1963, while Grimace and the Hamburglar became prominent members of the later McDonaldland cast.
