The Best Damn Thing is the third studio album by Canadian singer-songwriter Avril Lavigne, released on April 17, 2007, through RCA Records, as her first album on the label. The album represents a musical departure from her previous studio album Under My Skin (2004), which incorporated more elements of post-grunge. 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.
