"World on Fire" is a song by Canadian singer-songwriter Sarah McLachlan.

It was released in June 2004 as the third single from her Afterglow album (2003).

McLachlan wrote the song in the wake of the September 11 attacks.

It opens with the claim of having cost $150,000, despite the ensuing low-quality footage of a barefoot McLachlan in a plain room playing her guitar.

The video continues to reveal it actually cost $15, then tracking (in animated and videotaped segments) how the remainder went to enriching lives all around the globe through charitable donations.
