"Da Ya Think I'm Sexy?" is a 1978 hit song for Rod Stewart. It was written by Stewart and Carmine Appice, and produced by Tom Dowd.

"Da Ya Think I'm Sexy?" spent one week at the top of the British charts in December 1978 and four weeks at the top of the Billboard Hot 100, starting February 10, 1979.

The song was criticized by many in the rock press as a betrayal of Stewart's blues-oriented rock roots due to its disco-like arrangement, but Stewart and others were quick to point out that other widely respected artists, such as Paul McCartney and The Rolling Stones, had also released disco-flavoured songs.

Carmine Appice,who played drums on this song told Songfacts: "This was a story of a guy meeting a chick in a club. At that time, that was a cool saying. If you listen to the lyrics, 'She sits alone, waiting for suggestions, he's so nervous...' it's the feelings of what was going on in a dance club. The guy sees a chick he digs, she's nervous and he's nervous and she's alone and doesn't know what's going on, then they end up at his place having sex, and then she's gone."

In 2004 Rolling Stone ranked the song #301 on their list of The 500 Greatest Songs of All Time.

A 12" disco single of the song was released in 1978. The song was remixed by disco producer Jim Burgess. It ran one minute longer than the lp version at 6:29 and contained two alternate recorded lines and a heavier bass enthused drum beat.

A judgment in a plagiarism lawsuit by Brazilian musician Jorge Ben Jor ruled that the song had been derived from his composition "Taj Mahal". Stewart agreed to donate all his royalties from the song to United Nations Children's Fund.

"Taj Mahal" is recognisable (and was legally recognised in a plagiarism lawsuit) as the source of the melody in Rod Stewart's hit "Da Ya Think I'm Sexy?". "Taj Mahal" originally appeared on 1972's "Ben" album, becoming a big hit on the charts in Brazil that year.

Stewart performed the song at the Music for UNICEF Concert at the United Nations General Assembly in 1979. The song also lifts a musical refrain from Bobby Womack's 1975 song, "(If You Want My Love) Put Something Down On It".
