"Knocking at Your Back Door" is a song by the English hard rock band Deep Purple, the first track of the album Perfect Strangers, which was released in October 1984. The song was written by Ritchie Blackmore, Ian Gillan and Roger Glover. The track received heavy airplay at the time, playing on heavy rotation. It was used by the Seattle SuperSonics in their lineup intro during home games.

The song is lyrically about anal sex, as it uses various sexual innuendos throughout the song. Ian Gillan commented:

There's this guy named Redbeard, from a radio station down in Texas. He phoned me up after it had been played on every radio station in America and said, "Is this what I think it's about?" And I said, "Yeah." And he said, "It's amazing, every radio station in America is playing a song written about anal sex and they don't even realize what's going on." And I was like, well it's not in-your-face anal sex, it's just a joke. It just came about with the lyrics. It's no big deal. But it's a humorous thing and not meant to be offensive. And I think it was just an afterthought. It certainly wasn't what inspired the song.^[2]

After receiving considerable airplay,^[3] the song was released commercially in the US in December 1984, while in the UK, it was released as the second single from the Perfect Strangers album in June 1985.^[4]
