The Diary of a Madman Tour was the second concert tour by the English heavy metal singer Ozzy Osbourne. It was undertaken in support of Osbourne's second album Diary of a Madman and covered Europe, North America, and Asia. This was guitarist Randy Rhoads’ last tour as he died in a plane crash at a small airport in Leesburg, Florida, on 19 March 1982, during the North American leg of the tour. The band took a two-week break after his death. Ozzy and Sharon Osbourne restarted the tour with ex-Gillan guitarist Bernie Tormé, who only performed seven shows before being replaced by future Night Ranger guitarist, Brad Gillis.
