Slade Smashes is a compilation album by the British rock band Slade. It was released 1 November 1980 and reached No. 21 on the UK charts. The album was issued by Polydor in the wake of new interest in the band following their successful appearance at the 1980 Reading Festival, filling in for Ozzy Osbourne. The album featured most of the band's big hits from their early and mid 1970s heyday in the UK as well as three of the band's singles from post-1977. This collection, alongside the band's subsequent 1981 studio release We'll Bring the House Down, further cemented Slade's comeback in the UK and Europe.

Slade are an English rock band formed in Wolverhampton in 1966.

They were the first act to have three singles enter the charts at number one; all six of the band's chart-toppers were penned by Noddy Holder and Jim Lea.
