A CountryMusic group founded in 2002 by Kristian Bush, Kristen Hall and Jennifer Nettles. All three members had plenty experience: Kristian was formerly one-half of the folk rock duo Billy Pilgrim, Jennifer fronted an Atlanta-based band called Soul Miners' Daughter, and Hall had two solo albums. Creator/MercuryRecords signed the group in 2004. Their debut album ''Twice the Speed of Life'' sold triple-platinum and produced four hit singles.

After Kristen Hall left in 2006, Sugarland continued as a duo. It was then that the duo's career kicked into high gear. ''Enjoy the Ride'' produced Sugarland's first Number One hits, as well as a Grammy win for "Stay". It also sold three million copies. Jennifer sang a duet vocal on Music/BonJovi's "Who Says You Can't Go Home", which made Bon Jovi the first rock band to have a #1 country hit. ''Love on the Inside'' (2008) moved the duo to a more organic, acoustic sound which garnered critical acclaim for the most part. This album included three more #1 hits: "All I Want to Do", "Already Gone" and "It Happens". A fourth album, ''The Incredible Machine'', was released late in 2010, but "Stuck Like Glue" was the only hit from it.

After a stage collapse at a concert in Indiana in 2011 killed 7 fans and injured 45 more, the duo had 44 lawsuits filed against it. Since then, they have taken a hiatus from recording, but they continued to tour for a while afterward. Both Nettles and Bush have also continued to record independently during the hiatus.

In late 2017, the duo reunited on Big Machine Records for a new album, ''Bigger''.

!Tropes present:
* AutoTune: Used briefly in "Stuck Like Glue" on the backing vocals ([[SelfBackingVocalist all of whom are Jennifer Nettles]]) at the end.
* {{Bowdlerise}}: A variant. Some radio stations excised the reggae-rap bridge and the auto-tune bit from "Stuck Like Glue".
* CarefulWithThatAxe: The almost pained-sounding yowl Jennifer lets out at the end of "Down in Mississippi (Up to No Good)".
* ChristmasSongs: ''Gold and Green'', released in 2009. Before that, the duo released covers of "Winter Wonderland" and "Nuttin' for Christmas" as bonus tracks on ''Enjoy the Ride''.
* EarlyInstallmentWeirdness: Their debut album, the only one on which Hall was a member. It was the only one not produced by Byron Gallimore (Garth Fundis produced it instead), and it was more mainstream country with somewhat heavier lyrics. After Hall quit, Nettles and Bush shifted to a more acoustic pop sound with often lighter and more fun lyrics.
* [[EverytownAmerica Everyday America]]
* TheFourChordsOfPop: "Everyday America" uses IV-V-I-vi.
* [[GettingCrapPastTheRadar Getting Shit Past the Radar]]: Invoked on "It Happens", which intentionally sticks a "shh" before the title.
* LyricalShoehorn: "All I wanna do-oo-oo-oo-oo-ah-oo-oo-oo-oo-oo-ah-oo-oo-oo-oo-oo-oo-oo…"
* NeoclassicalPunkZydecoRockabilly: The reggae-rap bridge in "Stuck Like Glue".
* NiceHat: Kristian usually wears a cowboy hat or fedora.
* RedOniBlueOni: Nettles is very active and outgoing onstage, while Bush is more quiet and in the background.
* SelfBackingVocalist: The end of "Already Gone" is done as a round, which distinctly includes two vocal lines both sung by Jennifer.
* SoloSideProject: According to both members, their respective solo albums are meant to be this — despite both of them having a solo project going, both insist that Sugarland is merely on hiatus.
* {{Steampunk}}: The inspiration for the eponymous song from ''The Incredible Machine'' and the theme of its corresponding tour.
* StepUpToTheMicrophone: Kristian occasionally gets a shared lead vocal on album cuts. He also split the lead vocal when they, along with Music/LittleBigTown and Music/JakeOwen, covered "Life in a Northern Town" while on tour in 2008.
* TeenageDeathSongs: "Joey", in which the narrator laments the death of her boyfriend and asks what she could've done different.
* TitleOnlyChorus: "Tonight" for the most part.
