Main article: Under My Skin
Lavigne's second album, Under My Skin, was released on May 25, 2004, in the U.S. It debuted at number one in the U.S., the UK, Germany, Japan, Australia, Canada, Mexico, Argentina, Spain, Ireland, Thailand, Korea and Hong Kong and sold more than 380,000 copies in the U.S. in its first week.[23] Lavigne wrote most of the album with Canadian singer-songwriter Chantal Kreviazuk, though some tracks were co-written by Ben Moody (formerly of Evanescence), Butch Walker of Marvellous 3, her former lead guitarist Evan Taubenfeld, and her former drummer Matt Brann. Kreviazuk's husband, Our Lady Peace front man Raine Maida, co-produced the album with Butch Walker and Don Gilmore.
This album has a more alternative rock influence with some song with a goth-rock edge, others songs has a punk-pop influence, like He Wasn't and I Always Get what I Want, and a soft post-grunge sound, like "Freak Out" and "Who Knows"
Lead single "Don't Tell Me" went to number one in Argentina and Mexico, the top five in the UK and Canada, and the top ten in Australia and Brazil. "My Happy Ending" went to number one in Mexico and it reached the top ten in the U.S. making it her third-biggest hit there, but third single "Nobody's Home" did not make the top forty in the U.S., and it only went to number one in Mexico and Argentina. The fourth single from the album, "He Wasn't", reached top forty positions in the UK and Australia, and was not released in the U.S.[24] "Fall to Pieces" was released as the final single from the album, but did not do as well as previous singles.

She received five Juno Award nominations in 2005, picking up three, including "Fan Choice Award", "Artist of the Year", and "Pop Album of the Year". She won the award for "Favourite Female Singer" at the eighteenth Annual Nickelodeon Kids' Choice Awards.[25] Lavigne co-wrote "Breakaway" with Matthew Gerard, which was recorded by Kelly Clarkson for the soundtrack to the film The Princess Diaries 2: Royal Engagement (2004).[26] "Breakaway" was later included on Clarkson's second album, Breakaway, being released as the album's first single. The song peaked inside the U.S. top ten and provided Clarkson with a substantial hit.
Lavigne went on a "Live and by Surprise" twenty-one city mall-tour in the U.S. and Canada, starting on March 4, 2004, in Minneapolis, Minnesota, to promote Under My Skin. Each performance consisted of a short live acoustic set of songs from the new album. She was accompanied by her guitarist, Evan Taubenfeld. The venue in each city was not announced until forty-eight hours before the show. The tour was very popular and was successful in promoting the album. The set at Indianapolis on March 25, 2004, at Glendale mall included "He Wasn't", "My Happy Ending", "Don't Tell Me", "Take Me Away", "Nobody's Home", "Sk8er Boi", and "Complicated". Selections of this tour were released on the Avril Lavigne Live Acoustic EP, which was released in U.S. Target stores.
Lavigne was touring throughout most of 2005, and pursuing her acting and modelling careers. She represented Canada at the closing ceremony of the 2006 Winter Olympics in Turin, Italy, performing her song "Who Knows" during the eight minutes of the Vancouver 2010 portion.[27] The album has sold more than 12 million copies as of December 2007.
