Fall To Pieces is a song by Canadian singer/songwriter Avril Lavigne, and was the fifth and final single from her second album, Under My Skin (2004); it was the fourth single in the United States. It was produced and written by Avril Lavigne and Raine Maida. It was Lavigne's least successful single in the U.S., but it was a massive success in Canada. The music video shoot for the single was cancelled.

Fall To Pieces wasn't released in the United Kingdom, but it peaked at number seven on the Canadian BDS Airplay Chart, her third successful single in Canada after Nobody's Home and Don't Tell Me. It peaked at number sixteen in South Africa. Lavigne did not promote the single, and consequently it failed to chart on U.S. Billboard Hot 100; it peaked at number six on the Bubbling Under Hot 100 Singles chart, and at number fifty-five on the Billboard Pop 100.
