"Hey Mister Heartache" is a song by English pop singer Kim Wilde, released as the first single from her sixth studio album, Close (1988).

The song features vocals by Junior Giscombe; this part of the song was edited down for the single version.

The song was also extended for the 12-inch and CD-single formats, and a second 12-inch featuring the "Kilo Watt" remix by Timmy Regisford was also released in the UK.

Although a minor hit in Wilde's native UK, "Hey Mister Heartache" was a top-20 entry throughout Europe.

The music video contains an appearance by actor Jesse Birdsall.
