"7 Year Bitch" is a song from rock band Slade which was released as the second single from the 1985 album Rogues Gallery. The song was written by lead singer Noddy Holder and bassist Jim Lea. It was produced by John Punter.

Following the Top 15 success of the band's late 1984 single "All Join Hands", the band's first release of 1985 was "7 Year Bitch". The single was virtually banned by the UK broadcasting media which in 1985 was at the height of a wave of political correctness. As a result, the band felt unfairly judged by the media, who observed that they would have got away with it if they'd called it "7 Year Itch" and that no one complained about Elton John's The Bitch is Back which was a hit record in 1974. Later in 1998, Holder recalled of "7 Year Bitch's" potential, "That was a hit record, but we got a bit of a backlash". "7 Year Bitch" peaked at #60 in the UK and spent 3 weeks in the Top 100. Faring better in Germany, the song peaked at #39 and lasted on the singles chart for a total of eight weeks. It became Slade's last single of new material to enter the German Singles Chart.

In the September–December 1986 Slade International Fan Club Newsletter, the poll results were announced for the 1986 opinion poll based on Slade's material. For the best b-side of the 80s, "Leave Them Girls Alone" placed at #1.

Circa 1989, Lea revealed that he had done a re-worked version of "7 Year Bitch", although his version has remained unreleased to date. In the Slade International Fan Club Newsletter of April–June 1990, the third part of a late 1989 Jim Lea interview was published, where he spoke of the re-worked version amongst other tracks. He stated "I've also done another version of "She Did It to Me" with an ex-singer from Uriah Heap, with an absolutely panoramic version, it's great. I did a version of the old Johnny Kidd and the Pirates song "I'll Never Get Over You", you'd never know it was me though. I've also done "7 Year Bitch" but not like Slade's version and there is also some stuff that you've never heard of, but I haven't finished it yet. There is a track that I've written called "Radio Wall of Sound" and it sounds just like Slade, even my brother Frank says it sounds like Slade."
