The Best Damn Thing is the third studio album by Avril Lavigne, originally released in 2007.

The album represents a musical departure from her earlier studio album Under My Skin [MOVLP1772] which incorporates more elements of post-grunge music.

The Best Damn Thing is seen by critics as Lavigne's most commercial album and was noted as her first effort to feature a wide range of producers for the studio album, including Matt Beckley, Rob Cavallo, Dr. Luke and Lavigne herself.

The album received positive reviews from music critics, many praising her transition from grungy alternative rock music to more pop-punk music, with it being catchy and very radio-friendly.

The album debuted at number one in charts from the US, Austria, Canada, United Kingdom and many other countries. The album became one of the best-selling albums of 2007.

Four singles were released from the album. Its lead single "Girlfriend" peaked at number one on the Billboard Hot 100. The single also reached number one in twelve other countries across the world including Australia, Canada and Japan, making it one of the best-selling singles of 2007 worldwide. Other singles; "When You're Gone", "Hot" and "The Best Damn Thing" were successful around the globe.
