Cardiology is the fifth studio album by American pop punk band Good Charlotte. After various updates and uncertainty, it was finally announced the album would be released on November 2, 2010 through Capitol Records. Certain disruptions in the release involve the decision to re-record the entire album. As of September 2011, the album has sold over 52,000 copies.

On December 3, 2008, Kerrang! magazine announced that Good Charlotte would be releasing their fifth studio album, Cardiology in 2009. The title of which, according to Benji Madden, comes from the lyrical content of the album, which he explained: "all is connected to the heart". At the time, Madden also added that they had already written 20 songs for the album, and are said to be heading back to their pop punk roots.

Describing the sound to MTV news, Joel Madden said "There's nothing dance-y on the record, though, at all, which is different from our last one," further implying a movement away from the sound of Good Morning Revival, though some of the songs still are remniscent of it.

The band has been frequently giving fans updates about the album on their Twitter accounts. In late July 2009, Joel Madden mentioned that the band was close to track listing the album. On August 9, 2009, Benji Madden mentioned that they have yet to record the songs, but they are written.

He also gave fans a single line from one of the new songs:

Benji Madden also said on his Twitter account on August 26 that they are shooting for a March/April release date. "We are shooting for March/April guys. sorry for the wait but we wanna do this one right. Don't worry, you will get some music before then". On September 22, 2009, Joel Madden made a tweet that he was tracking vocals for a song called "There She Goes", and on September 29, 2009, he mentioned he tracked vocals for the song "1979". On October 14, 2009 Benji Madden posted a blog on the official Good Charlotte website describing the album's sound as "a more mature version of our self titled album... really simple production, just all about the songs and the lyrics. There will definitely be some surprises though, wouldn't be a GC record if there weren't right?" He also continues in his blog with lyrics from one of the new songs on the album called "Standing Ovation" with the lines:
