What is the name of McDonald’s worldwide campaign launched in 2003?

“I’m Lovin’ It” is the McDonald’s worldwide campaign launched in 2003.

The campaign introduced a short, conversational phrase that could work across different countries and languages. Its branding combined the slogan with a distinctive musical hook and the company’s established Golden Arches identity. McDonald’s used it across television, radio, packaging, restaurants and digital advertising.

The campaign was notable because it was designed as a global platform rather than as a slogan limited to one national market. Local executions could vary, but the central phrase remained recognizable. The campaign is also associated with a song recorded by Justin Timberlake and with music produced by The Neptunes.

People sometimes confuse the launch with earlier McDonald’s slogans such as “You Deserve a Break Today.” Those campaigns belong to different eras. “I’m Lovin’ It” is the phrase McDonald’s introduced in 2003 and continued using as a major international brand line.
