Joe Walsh's Greatest Hits – Little Did He Know... is the fourth compilation released by guitarist Joe Walsh. It contains his best-known solo songs as well as those he recorded with the James Gang and Barnstorm, but it does not contain material he released as a member of the Eagles. The 2006, digitally re-mastered re-issue of the compilation, titled "Joe Walsh: The Definitive Collection," has the same cover art except for differing text above the photo and no text below the photo.
