Adrenalize is the fifth studio album by English rock band Def Leppard, released on 30 March 1992 through Mercury Records.

It is the first album by the band recorded without guitarist Steve Clark, who died in 1991, although most songs were written and partially demoed before his death, they were re-recorded solo by Phil Collen in 1991-1992.

Clark was involved in writing six of the songs on the album,[10] but was given an ultimatum over his alcoholism in September 1990, and put on a six-month leave of absence.

The band tried to continue the recording process, going back into the studio the day after Clark's death to cope with the loss, but it took a few months before they were able to work to what they felt was a satisfactory standard.

The album received mixed reviews: some critics praised its production values and instantly catchy and radio-friendly material, while others called it tired and formulaic.

Considine wrote: "Adrenalize is so relentlessly catchy that it almost seems as if the band is about to abandon its heavy-metal roots for the greener fields of hard pop.

A staff writer for Sputnikmusic said that, despite the slick production, the album doesn't match the standard set by the band's previous two records, which they referred to as masterpieces.
