"Long Shot" is a song by American singer Kelly Clarkson, from her fourth studio album, All I Ever Wanted (2009). Written by Katy Perry, Glen Ballard, and Matt Thiessen, it was originally recorded by Perry (along with the single "I Do Not Hook Up") for an unreleased album and was later re-recorded by Clarkson. It is a pop rock song about taking a chance on pursuing a flawed relationship in spite of it being a "long shot."

The song received mixed to positive reviews from critics, who found it to be a "fun" pop song but also generic and unmemorable. In early 2010, the song was played on Canadian radio and entered that country's Hot AC airplay chart monitored by Nielsen N.V. despite no official single release or promotion from Clarkson's label.

The song was written by Katy Perry, Glen Ballard, and Matt Thiessen as a track for an unreleased album by Perry conceived sometime between the recording of Katy Hudson (2001) and One of the Boys (2008). When Perry was dropped from the Def Jam label and the project was scrapped, "Long Shot" and "I Do Not Hook Up" were given to RCA Records for Clarkson to record for her then-upcoming album, All I Ever Wanted. Clarkson's rendition was recorded by Mike Plotnikoff in 2008 at Bay7 Studios, Sparky Dark Studio, and Sunset Sound Studios, all located in Los Angeles County, California.
