Deacon Blue are a Scottish pop rock band formed in Glasgow in 1985, currently consisting of vocalists Ricky Ross and Lorraine McIntosh, drummer Dougie Vipond, guitarist Gregor Philp and bassist Lewis Gordon. In 2013, their estimated album sales stood at six million, and by 2020 were estimated to have risen to in excess of seven million, with twelve UK top 40 singles, along with two number one albums in both the United Kingdom and their native Scotland.

The band released their debut album, Raintown (1987) to critical and commercial success, with their second album, When the World Knows Your Name (1989), topping the UK Albums Chart for two weeks. The single "Real Gone Kid" became their first top ten single in the UK Singles Chart and reached number one in Spain. Deacon Blue followed up the success of their first two albums with Fellow Hoodlums (1991) and Whatever You Say, Say Nothing (1993). The band split in 1994 until five years later, holding a reunion gig which led on to a new album, Walking Back Home (1999). The band released another album, Homesick (2001), the last to feature guitarist Graeme Kelling; he died from pancreatic cancer in 2004. In 2006, the band recorded three new songs for a Singles album – including the single "Bigger than Dynamite".

Deacon Blue returned after a period of absence to release The Hipsters (2012), their first studio album since Homesick in 2001. The band released a further four albums following their reunion – A New House, (2014), Believers (2016), City of Love (2020) and Riding on the Tide of Love (2021) to commercial success. In 2024, they released "Late '88" as the lead single from their eleventh studio album The Great Western Road (2025).

Taking their name from the 1977 Steely Dan song "Deacon Blues", Deacon Blue were formed in 1985 following Ricky Ross's move from Dundee to Glasgow. Along with Ross, the group originally consisted of Lorraine McIntosh, James Prime, Dougie Vipond, Ewen Vernal and Graeme Kelling.

Ross, a former school teacher originally from Dundee, was the group's frontman, penning the majority of Deacon Blue's songs. He married vocalist Lorraine McIntosh in 1990. In 1986, the band contributed a track ("Take the Saints Away") to a compilation cassette entitled "Honey at the Core", featuring then up-and-coming Glasgow bands, including Wet Wet Wet, The Bluebells, Kevin McDermott, The Big Dish, and Hue and Cry.

The band's debut album, Raintown, produced by Jon Kelly was released in 1987. It spawned the singles "Dignity", "Chocolate Girl" and "Loaded". The city that the album's title refers to is Glasgow and the cover art of the album is a photograph (by the Scottish-Italian photographer Oscar Marzaroli) of the River Clyde's docks taken from Kelvingrove Park. It proved a commercial success and has to date sold around a million copies, peaking in the UK Albums Chart at no. 14 and remaining in that chart for a year and a half. On 27 February 2006, Raintown was reissued as part of Columbia's Legacy Edition series. The reissue was expanded to two CDs, the first of which featured the original 11 track album. The second CD featured alternate cuts of all 11 album tracks, as well as the two original CD bonus tracks "Riches" and "Kings of the Western World". The new edition did not include the varied bonus cuts (remixes and b-sides) that were found on the singles from the album.

The second album, 1989's When the World Knows Your Name, was the band's most commercially successful, reaching No. 1 in the UK Albums Chart and generating five UK top 30 hits, including "Real Gone Kid", "Wages Day", and "Fergus Sings the Blues" (all five singles from the album were top 10 hits in Ireland). The following year saw the band play in front of an estimated 250,000 fans at the free concert on Glasgow Green, "The Big Day", which was held to celebrate Glasgow being named that year's European City of Culture. The band also played Glastonbury and the Roskilde festivals that summer, as well as released Ooh Las Vegas, a double album of B-sides, extra tracks, film tracks, and sessions which reached No. 3 in the UK Albums Chart.

Jon Kelly returned to the producer's chair in 1991 for the album Fellow Hoodlums. The album was met with more critical approval and peaked at No. 2 on the UK Albums Chart. Fellow Hoodlums was followed up by 1993's Whatever You Say, Say Nothing, a much more experimental album. The album was not as commercially successful as the previous two albums, peaking at No. 4 on the UK Albums Chart. Changing from producer Jon Kelly to the team of Steve Osborne and Paul Oakenfold, this album presented a change in musical style for Deacon Blue. While the band's songwriting remained based in rock and blues, many of the tracks moved into alternative rock territory in their presentation.^{[citation needed]}
