The Single Factor, released in 1982, is the ninth studio album by English progressive rock band Camel. The title refers to the fact that guitarist Andy Latimer was the sole remaining original member, though original keyboardist Peter Bardens makes a guest appearance on 'Sasquatch'. The album was essentially a contractual obligation album, created under pressure from Decca Records to produce a hit single, and the "made-to-order" nature of its composition resulted in a selection of songs which can be described as "odd". Unlike previous Camel albums, all the songs were around 3–4 minutes.
The album was reissued on 8 September 2009 by Esoteric Recordings with a bonus version of "You Are the One".
