"Do They Know It's Hallowe'en?" is a charity record inspired by "Do They Know It's Christmas?". It was released on October 11, 2005, in Canada on Vice Records by a cast of rock artists and other performers under the name "North American Halloween Prevention Initiative" (NAHPI). It reached number four on the Canadian Singles Chart.
It was written by Nick Diamonds and Adam Gollner. Like its inspiration, it is a charity song, with all proceeds being donated to UNICEF. According to the official press release, the song "stems from a frustration with other benefit songs' misguided, somewhat patronizing attitude, and Western-centric worldview."
