"Last Dance" is a 1978 song by American singer Donna Summer from the soundtrack album to the 1978 film Thank God It's Friday. It was written by Paul Jabara, co-produced by Summer's regular collaborator Giorgio Moroder and Bob Esty, and mixed by Grammy Award-winning producer Stephen Short, whose backing vocals are featured in the song.

"Last Dance" became a critical and commercial success, winning the Academy and Golden Globe Award for Best Original Song, the Grammy Award for Best Female R&B Vocal Performance, and peaked at number three on the Billboard Hot 100 chart, all in 1978.

Summer has a role in the film Thank God It's Friday as an aspiring singer who brings an instrumental track of "Last Dance" to a disco in hopes the disc jockey will play the track and allow her to sing the song for her fellow patrons; after refusing through most of the film the disc jockey eventually obliges Summer's character and her performance causes a sensation.

According to the song's co-producer and co-writer Bob Esty, Paul Jabara had locked Summer in a Puerto Rico hotel bathroom and forced her to listen to a cassette of him singing a rough version of "Last Dance." Summer liked the song and Jabara asked Esty to work with him on an arrangement for Summer to make her recording. Esty recalls:

I changed some of the chords and extended the 'hook' to repeat three times to finish the last phrase of the chorus. I also added a bridge to build to a climax and suggested a ballad intro à la "Ain't No Mountain High Enough" and another ballad in the middle of the song building again to a high note for the last chorus ending. To our knowledge, this had never been done in a disco track. ..We did the piano/vocal with Donna and me of the full version including the two ballad sections and the ending in one 'pass'...I recorded the full track in one day, rhythm in the morning, horns and strings during the day. That same night, Giorgio Moroder recorded Donna's vocal exactly as she sang the demo, in two takes, and banning me from attending the session. In spite of the fact Giorgio didn't like the song and didn't want Donna to sing in a full voice style, I thought I would be at least credited for co-producing the track and co-writing the song with Paul. He ultimately took credit for it. And Paul Jabara took the Oscar. I learned a bitter lesson from that.
