"Stumblin' In" is a song written by Mike Chapman and Nicky Chinn, performed by Chris Norman and Suzi Quatro.

The writing-producing team of Mike Chapman and Nicky Chinn were behind many of the 1970s hits for Suzi Quatro and for Chris Norman's band Smokie.

In 1978, Chapman, Chinn, Quatro, and the members of Smokie were all at a party in Düsseldorf.

As Chapman recounted, "Suzi was playing bass, and Chris was there with his arm round her, and they were singing into a mike, and I thought what a fantastic duet they’d make, because they looked so great together.

[5] In 2021, the song was used in the Paul Thomas Anderson film, Licorice Pizza.
