Dehumanizer is the sixteenth studio album by English rock band Black Sabbath. It was first released on 22 June 1992 in the UK by I.R.S. Records and on 30 June 1992 in the US by Reprise Records.

It was Sabbath's first studio album in over a decade to feature vocalist Ronnie James Dio and drummer Vinny Appice, and their first in nine years to feature original bassist Geezer Butler. Initial writing and demo sessions at Rich Bitch Studios in Birmingham featured drummer Cozy Powell; bootlegs of these sessions exist. However, when Powell became injured with a broken hip, he was replaced with Appice. With Appice back in the band, this effectively reunited the Mob Rules lineup. The band spent two weeks writing material before spending six weeks rehearsing and recording demos at Monnow Valley Studios in Wales.

The album's lineup – Dio, Appice, Butler and guitarist Tony Iommi – reunited in 2006 for a greatest hits set, Black Sabbath: The Dio Years, and a new studio album in 2009, The Devil You Know (billed as Heaven & Hell).

The album was re-released, with bonus content, on 7 February 2011.
