Bark at the Moon is the third studio album by the English heavy metal singer Ozzy Osbourne, released in 14 November 1983 in the US and on 2 December 1983 in the UK.

The album marks Ozzy’s change to a synth infused pop-metal sound, with both its “sonic production, and in Ozzy’s imaging”.

A commercial success, Bark at the Moon peaked at number 19 on the Billboard album chart and within several weeks of release was certified gold for over 500,000 sales in the United States. By 2000, it had sold over 3,000,000 copies in the United States.

In the UK, it was the third of four Osbourne albums to attain silver certification (60,000 units sold) by the British Phonographic Industry, achieving this in January 1984.

The album was remastered on CD in 1995 and again (with a different mix) in 2002. This is Osbourne’s first album to feature guitarist Jake E. Lee and only studio album to feature drummer Tommy Aldridge.
