The Best Damn Thing is the third studio album by Canadian singer Avril Lavigne. It was released on 17 April 2007, by RCA Records. The album represents a musical departure from her earlier studio album "Under My Skin" (2004), which incorporates more elements of post-grunge music. "The Best Damn Thing" is seen by critics as Lavigne's most commercial effort. The album was noted as her first effort to feature a wide range of producers, including Matt Beckley, Rob Cavallo, Dr. Luke and Lavigne herself, who was credited as the executive producer.
