Paranoid is the second album by the British heavy metal band Black Sabbath. It was released in the United Kingdom during September 1970, and contains some of their most famous work, including the songs 'Iron Man', 'War Pigs' and the title track. The album is regarded as a classic of the heavy metal genre and one of the most influental heavy metal albums. It has been certified 4x Platinum, having sold over four million copies in the US alone, making it Black Sabbath's best-selling album.

The 'Paranoid' single, released before the album, reached number four in the UK. Pushed by its success, the album hit number one in the UK, and is the only Black Sabbath album to have done so. The US release was held until January 1971, as the Black Sabbath album was still on the charts at the time of Paranoid's UK release. The album broke into the top ten in the US in March 1971, and would go on to sell four million copies in the US alone, with virtually no radio airplay.
