(AMPROFON). Eilish included the song on the setlists of her 2019 When We All Fall Asleep Tour and her 2020 Where Do We Go? World Tour, and again on her 2022 Happier Than Ever, The World Tour.

Background and release
"Bellyache" was released for digital download and streaming on February 24, 2017, as the second single from Eilish's debut EP Don't Smile at Me, through Darkroom and Interscope Records. The track was written by Eilish and her brother Finneas O'Connell, known under his stage name of Finneas, with him solely handling production. Mastering and mixing were handled by studio personnel John Greenham and Rob Kinelski, respectively. In December 2021, American rapper Doja Cat revealed that she was asked by Eilish to feature on the track during its early stages of development, yet declined since she was experiencing writer's block at the time. In an interview with Teen Vogue, Eilish stated that "Garbage" (2013) by American rapper Tyler, the Creator was the biggest inspiration for the song: "'Garbage' was one of the biggest inspirations for writing my song, 'bellyache'. It's more graphic than my song, it's more literal and 'I'm killing people and putting them in my basement' kind of song. I'm a huge fan of Tyler, he's been my biggest inspiration ever." A remix of the song was created by Marian Hill, an American songwriting duo, and was released on May 5, 2017 for digital download. Dan Regan of Billboard praised the remix, saying it "amplifies the off-center feel with a wonky, futuristic take". He continued, writing that the "groove is sly and just a little crazed".

Composition and lyrics
Critical commentary described "Bellyache" as a midtempo electropop, R&B, and alt-hip-hop song. It has influences of hip hop, deep house, and Latin macabre in the instrumentation. According to sheet music published by Universal Music Publishing Group at Musicnotes.com, "Bellyache" is composed in the key of E minor, at a moderate tempo of 100 beats per minute. Eilish's vocals span a range of E 3 to B 4. Jason Lipshutz of Billboard mentioned that "Bellyache" has "macabre lyrics around a delectable pre-chorus hook and a steady acoustic pattern that eventually gives way to a sizzling drum machine".

The lyrics were inspired by the childhood guilt she felt after stealing toys from friends and her crippling stomach pains. Eilish said that is about "the concept of guilt". The song's lyrics were written from an entirely fictional perspective of a psychopath who kills those she is close to, including her friends and lover. Eilish takes on the persona of the psychopath who has killed her friends and dumped their bodies in the back seat of her car. She also sings about killing her lover and ditching his body in a gutter. The song's lyrics reference action film V for Vendetta (2005). Eilish told Paper magazine the plot of the song: "[The] [song] [is] [about] killing people and feeling guilty about it. [It's about] getting a bellyache because you just killed a bunch of people, which you would if you just killed a bunch of people if you were human. We kind of just became this character that knows they're out of their mind, but also doesn't at the same time."

Critical reception
"Bellyache" was met with mostly positive reviews from music critics, with a number of them praising the lyrics and production. Mike Wass, writing for Idolator, called it a "sinister synth-anthem that positively seethes fury and frustration". Writing for Elle magazine, Estelle Tang labeled the song as a "banger about bad decisions". Eve Barlow of Vice described "Bellyache" as "totally psycho" and "perfectly pop". Meaghan Garvey, writing for The Fader, cited the track as a "loping" and "cowboy-ish number with a touch of deep-house bounce". Ilana Kaplan of Paper noted that while Eilish's 2016 singles "Ocean Eyes" and "Six Feet Under" are more pop, "Bellyache" has "more of an R&B production angle", and admitted it would become more prominent as Eilish released more songs in the future.

Mark Savage lauded the song in his review for BBC News, saying it is the "pop equivalent" to the works of Quentin Tarantino, and finds "comic absurdity in the midst of eye-popping gore". The staff of LadyGunn compared the track to "Ocean Eyes", saying it "evoke[s] a darker Lorde over a trap-infused beat". Writing for Atwood Magazine, Nicole Almeida commented that "Bellyache" gets "better with every listen". She elaborated, mentioning that "the casual guitar strums coupled with Eilish unapologetic embodiment of [the] character and beats really challenge you not to move to them". Almedia concluded by calling the song "one of the EP's highlights". Adrien Begrand from PopMatters affirmed the song shows Eilish's "precocious talent".

NME ranked "Bellyache" at number four on their 'Every single Billie Eilish song ranked in order of greatness' list. The staff described it as "a twisted song, but with a pinch of wry humor". Insider's described the lyrics as "violent" and "dark", commenting that they "belie the song's quietly upbeat melody", and prove Eilish and Finneas as "some of the most talented and versatile artists making music today".

Music video
An accompanying music video was uploaded to Eilish's YouTube channel on March 22, 2017, and was directed by Miles and AJ. In it, Eilish is shown stranded in the middle of a deserted highway which is Mojave-Tropico Road in California. The sky is a shade of purplish-blue, and the sides of the pavement are marked with cacti and sand. She is dressed from head to toe in a yellow ensemble. The video begins with Eilish walking down a long, empty desert road, dragging a red wagon filled with garbage bags, which she eventually reveals to be full of cash. Eilish starts to recount the bad things she has done, "Where's my mind?" she wonders, before forgetting about it: "Maybe it's in the gutter, where I left my lover". Throughout the video, Eilish throws dollar bills in the air and dances along the highway.

The music video was positively received by critics. De Elizbeth of Teen Vogue said the video "definitely invokes feelings of summertime", and that it will "make you want to find your best romper and sunnies and be outside". Ian David Monroe, writing for V magazine, described the visual as "a little silly", but said it was "seriously well-produced". Writing for Nylon magazine, Sydney Gore compared Eilish's look in the visual to that of Uma Thurman in the 2003 American film Kill Bill. Gore also praised the choreography, saying that "we're experiencing hallucinations as we watch her bust out some sick down the road which leads to the great unknown". Jacob Moore of Complex magazine labeled the video as "bright", "mischievous" and "captivating".

Nate D. Sanders auctioned a yellow rain suit and jacket nearly identical to the outfit worn by Eilish in the music video for 12,000 dollars in February 2020. Instead of an "X" on the front of the outfit, Eilish's full name is signed in block letters on the right shoulder and her last name is written in cursive across the front of the overalls. The listing stated: "Outfit was worn by Eilish on several occasions according to the accompanying COA from MusiCares charity. A quintessential example of Billie Eilish's personal style, worn and signed by the 5-time Grammy award winner."
