"Night Fever", is a disco song, written and performed by The Bee Gees. It first appeared on the soundtrack to Saturday Night Fever. Producer Robert Stigwood wanted to call the film Saturday Night, but singer Robin Gibb expressed hesitation at the title. Stigwood liked the title Night Feverbut was wary of marketing a movie with that name. He combined the two suggestions and the idea for Saturday Night Feveras a motion picture was born.

"Night Fever" remained the number one Billboard Hot 100 single for over two months in 1978. It also replaced Andy Gibb's "Love Is Thicker Than Water" at number one, and was in turn replaced by Yvonne Elliman's "If I Can't Have You" - all of which were written and produced by the Gibb brothers.

After the success of "Night Fever," the Governor of Florida, Reubin O'Donovan Askew, made the three men "honorary citizens" of the state, due to the amount of time they spent each year recording singles in Miami.

In addition to Saturday Night Fever, the song has also appeared in the movie and on the soundtrack for Mystery Men.

A rare music video was made for the song in 1978, however it wasn't shown to the public until 2004 despite the fact the video didn't contain any uncensored content. It features the brothers singing the song in a dark studio cut with images from New York City streets. An interesting note, in the video Barry Gibb was shown without his trademark beard.

The song lists at #33 on Billboard's All Time Top 100.[1]

Texan punk rock band The Dicks covered this song on the B-side of their 1980 debut single "Hate the Police" under the title "All Night Fever".

In 2008, Australian singer and songwriter Tina Arena performed a cover version of "Night Fever" for the French film Disco.
