What is McDonald's current global tagline, launched in 2003?

McDonald's global tagline launched in 2003 is “I'm Lovin' It.”

The phrase was introduced during a major worldwide branding campaign intended to give McDonald's a consistent contemporary identity across markets. It was written in the first person, making the slogan sound like a customer's personal reaction rather than a direct corporate claim.

The campaign used the English phrase internationally, often alongside local-language advertising. Its musical identity became particularly prominent, helping the line function as both a slogan and an audio brand cue.

People sometimes associate the campaign only with the “ba da ba ba ba” jingle, but the words and the musical signature were separate elements of the broader branding program. The tagline followed earlier McDonald's slogans such as “You Deserve a Break Today.”
