"Over the Mountain" is the opening track of heavy metal musician Ozzy Osbourne's album Diary of a Madman. The song debuted at number 42 on the Billboard Top Tracks chart and reached number 38. The song was written by Osbourne, Bob Daisley, Lee Kerslake and Randy Rhoads. The song was later included on the Ozzy Osbourne compilation albums, The Ozzman Cometh on 11 November 1997, The Essential Ozzy Osbourne on 11 February 2003 and Prince of Darkness on 22 March 2005.

Prince of Darkness is a box set of four CDs by Ozzy Osbourne released in 2005. The first two CDs are Osbourne's solo work containing various studio recordings, live tracks, b-sides, demos and outtakes, and the last two CDs are collaborations on disc three and cover songs on disc four. The cover versions were recorded for this box set compilation, but were released on a stand-alone album entitled Under Cover later in the year.
