"Who Do You Think You Are" is a song written by the British songwriting-team Des Dyer and Clive Scott. The song was first recorded by the pop group Candlewick Green and released in late December 1973. The song peaked at #21 in February 1974.

In 1974 Dyer and Scotts's pop group Jigsaw recorded the song as an album track on their 1974 studio album; I've Seen The Film, I've Read The Book.

The song has since been covered by many artists. Most notably by the US group Bo Donaldson and the Heywoods also in 1974 (peaking at #15 on the Billboard Hot 100), and the British indie dance/indie pop band Saint Etienne with an alternative dance-pop arrangement in 1993 (peaking at #23 on the UK Singles Chart as a double a-side with "Hobart Paving").

All tracks written and composed by Dyer and Scott; except where indicated.
