Who performed the English-language jingle for McDonald’s “I’m Lovin’ It” campaign?

Justin Timberlake performed the English-language jingle for McDonald’s “I’m Lovin’ It” campaign.

McDonald’s launched the campaign in 2003 as its first global advertising platform. The campaign used a short phrase, a recognizable five-note musical hook, and localized versions intended for audiences in many countries. Timberlake’s vocal performance helped connect the English-language version with a major contemporary pop artist.

Pharrell Williams is often mentioned alongside the campaign because he was involved in producing the music. That association can lead people to identify him as the singer, but Timberlake performed the vocal jingle used in the English-language campaign material.

The campaign was unusually important in McDonald’s branding history because it sought to make one identity work internationally while still allowing local adaptation. Its phrase and musical signature became more enduring than many individual advertisements and continued to appear in McDonald’s marketing for years afterward.
