"Islands in the Stream" is a 1983 hit country and pop single, written by the Bee Gees and sung by Kenny Rogers and Dolly Parton. It was the first single from Rogers' album Eyes That See in the Darkand the second pop number-one for both Rogers and Parton (Rogers having been there with 1980's "Lady" and Parton with 1981's "9 to 5"). They went on to record a Christmas album together, and had an additional hit with their 1985 duet "Real Love". The Gibbs originally wrote the song for Diana Ross in an R&B style, only later to change it for the Kenny Rogers album.

It also spent two weeks as the number one country song and in the year's final countdown was the number one song of the year of 1983. In Australia, the song was number one for one week in December 1983 and becoming one of the highest selling singles of 1984. In 2005, the song topped CMT's poll of the best country duets of all time; Parton and Rogers reunited to perform the song on the CMT special.

In April 2008, South Bend, Indiana radio station WZOW played the song continuously for several days on end. This was a stunt used to draw attention to the station's format change from alternative rock to adult contemporary.

In many ways it was a rather typical Bee Gees song with a straightforward rhythm in the verses being dissolved by a unique chorus with heavily syncopated lyrics strongly contradicting the still basic rhythmic patterns of the melody. The unusual traits of the chorus has been described as "the words coming almost half a beat too late".

In March 2009, actors Ruth Jones and Rob Brydon, in character as Vanessa Jenkins and Bryn West from the hit BBC show Gavin & Stacey, released a version of the song as a single for Comic Relief. Robin Gibb and Sir Tom Jones appear on the single as backing singers. Titled "(Barry) Islands in the Stream" in reference to the Barry Island setting of Gavin & Stacey, it entered the UK Singles Chart at number 1 on 15 March 2009.

The chorus with reworked lyrics was featured on Pras Michel's 1998 hit song "Ghetto Supastar (That Is What You Are)". This version of the song featured ODB (Old Dirty Bastard) and Mýa, and appeared on the Bulworth soundtrack.,
