"LoveGame" is a song released by American singer Lady Gaga from her debut studio album, The Fame (2008). Produced by RedOne, the track was released as the album's third single in North America and Europe and the fourth single in Australia, New Zealand, and Sweden after "Eh, Eh (Nothing Else I Can Say)". "LoveGame" was also released as the fourth single in the United Kingdom, after "Paparazzi".

Critics appreciated the song's rhythm and the "I wanna take a ride on your disco stick" hook. Gaga had explained that the term "disco stick" is a euphemism for a penis and was inspired by her sexual attraction to a stranger at a night club. Musically carrying the vibe of underground New York discos, "LoveGame" talks about love, fame, and sexuality which was the central theme of the album. The song received a number of remixes, one of them featuring rock musician Marilyn Manson. "LoveGame" was a commercial success, charting within the top ten in the United States, Australia, New Zealand, Canada, France, Germany, and other European countries. It became Gaga's third consecutive number-one song on the Billboard Mainstream Top 40 chart and achieved triple platinum certification from the Recording Industry Association of America (RIAA).

The New York underground-inspired music video for the song was directed by Joseph Kahn, and portrayed Gaga dancing at an underground subway station and in a parking lot. The music video was a tribute from the singer to the New York lifestyle including its glamour, fans and fashion. It was influenced by the music video for Michael Jackson's "Bad", which also took place in a subway station, and features Gaga wearing Nazi chic clothes. The music video was banned from broadcast at the PG-rated time slots in Australian television channels because of its sexual content. "LoveGame" has been performed live a number of times by Gaga, including television appearances, such as Dancing with the Stars and The Ellen DeGeneres Show, the 2009 MuchMusic Video Awards, and many of the singer's concert tours. She usually performs the song while holding her characteristic "disco stick" in one hand.

Towards the end of 2007, Lady Gaga's management company introduced her to songwriter and producer RedOne, whom they also managed. By 2008, Gaga relocated to Los Angeles in order to work extensively with her record label to complete her debut album, The Fame, and set up her own creative team called the Haus of Gaga. "LoveGame" was one of the songs written by Gaga and RedOne who also produced the track. With Rolling Stone, Gaga explained that she was at a nightclub and had a "sexual crush" on somebody. She went up to the person and uttered the line, "I wanna ride on your disco stick". Thinking it to be a thoughtful metaphor for penis, Gaga went to the recording studio the next day and wrote the song in roughly four minutes. Gaga also had ideas for the live performance of the song where she used "an actual stick—it looks like a giant rock-candy pleasuring tool—that lights up".

While commenting in regards to the lyrical content of the song on Australian talk show, Rove, Gaga said that she was unrepentant about her "disco stick" metaphor, though it led to a banning of the music video on Network Ten in Australia. She added that the metaphor was not meant to be subtle and was clear what the lyrics constituted off. "If anything, I happen to think people are frivolously hard on me", Gaga generalized. She went on to relegate "lot of youth-oriented pop music" as much racier than hers with their sexually provocative lyrics, but Gaga felt that the whole context of her visuals alongside the music was what made people react. "It's the music in relation to the visual, in relation to the way I move and the way I articulate the lyrics. But if I wanted to make music to make people sing 'la di da' that would be very boring," she concluded.

"LoveGame" was released as the album's third single in North America and Europe and the fourth single in Australia, New Zealand, and Sweden after "Eh, Eh (Nothing Else I Can Say)". In the US it was sent to Contemporary hit radio (CHR) formats for airplay from May 12, 2009. The track initially had been planned as the third single release in the United Kingdom, but deeming its lyrics and music video potentially controversial, it was decided that "Paparazzi" would be released instead. "LoveGame" has received a number of remix treatments, one of which featured vocals from rocker Marilyn Manson. Daniel Kreps from Rolling Stone reported that the remix was conceived during Gaga's photoshoot with the magazine in May 2009, when Manson arrived on the set. The rocker was impressed by the shoot and wanted to collaborate with Gaga on "LoveGame".

"LoveGame" was recorded at Record Plant Studios and Chalice Recording Studios, both in Hollywood, California. Along with the production work of the track, RedOne also contributed to its background vocals, instrumentation, programming, audio engineering and recording. Other personnel involved in creating the final version of the song included Robert Orton who did the audio mixing, and Gene Grimaldi who mastered the song at Oasis Mastering in Burbank, California.

Musically, "LoveGame" is an uptempo synth-pop and electro-R&B song. According to Kerri Mason of Billboard, the composition has a vibe of the New York downtown musical scene, but has a more mainstream appeal to it, making it perfect for radio, "without losing its smut and sass". The song does not have a massive sound like previous single "Poker Face", nor has a big melody like subsequent single, "Paparazzi". Instead the composition of the song is electro-R&B, consisting of big beats and a number of hooks, with Gaga repeating the word "huh!" from time to time.

Gaga explained that the lyrics of "LoveGame" were clear about what the song is all about. She thought that the lyrics portrayed a powerful message about love, fame, and sexuality which was the central theme of The Fame. According to the sheet music published at Musicnotes.com by Sony/ATV Music Publishing, "LoveGame" is set in the time signature of common time and is composed in the key of B minor with a moderate tempo of 104 beats per minute. Gaga's vocal range spans from B₃ to G₅. It follows in the chord progression of Bm–Em–D–Bm–Em–D in the first two verse and chorus while progressing as Bm–Em–Bm–Em in the intermediate verse before the final chorus.

The song received mostly positive reviews from critics. The Phoenix music editor Daniel Brockman said that "Gaga ups the ante in terms of catchy song writing and sheer high-in-the-club-banging-to-the-beat abandon." He also commented on the lyrics saying that "'Let's have some fun, this beat is sick / I wanna take a ride on your disco stick' might be the trashiest-yet-awesomest refrain I've heard on a major-label record this year." Sal Cinquemani of Slant Magazine criticized the song for "cheap" lyrics and "painfully enunciat[ing] without any resemblance of actual sex appeal". While reviewing The Fame, BBC said that the song sounded robotic in the line "I wanna take a ride on your disco stick", though deemed it a brilliant track which "leaves us awarding Gaga the yearbook title of 'pop star most likely to kill'."

Nick Levine from Digital Spy believed that lines like "I wanna take a ride on your disco stick" was a direct reason of Gaga's commercial success. Although he felt that the song was "attention-seeking", he knew that it would provoke reaction from the masses, be it good or bad. Genevieve Koski from The A.V. Club called the song as a "propulsive club anthem" and complimented its synths and drum programming. She described it aurally as "a dizzying sonic trip that approximates the high point of a chemically enhanced night of club-hopping." Evan Sawdey from PopMatters complimented RedOne's production on the song, listing it as one of the best tracks on The Fame.

Ben Hogwood from MusicOMH declared the song as "top notch, diamond-encrusted pop" along with other tracks like "Starstruck" and "Paparazzi". He found the lyrics to be sometimes odd, especially the statement, "I'm on a mission, and it involves some heavy touchin'." Sarah Rodman of The Boston Globe said that the song "has a gutter level quippage with sinuous moves". Priya Elan from The Times was not impressed with the song and called it calculated. Billboard music editor Chris Williams gave the song a positive review, commenting that "It has all the winning ingredients of its predecessors: a radio-friendly, club/electropop feel; a provocative, yet silly enough catchphrase and hook; and a dash of '80s synth magic, so the adults can play along. On 'LoveGame' Gaga is in it to win it."

While reviewing The Fame on its fifth anniversary, Bradley Stern from Idolator noted that "LoveGame" could "easily be erased from Gaga's back catalog with little consequence" since he felt it to be nothing more than an "electro-dance" track. But Stern believed that "LoveGame" was an important component of Gaga's career trajectory, since it was the last testament of her image as "that of the disco-stick wielding pop star from out of space"—the image was later deconstructed as the doomed starlet in the music video of "Paparazzi". He concluded by saying that the song "is a wonderful moment of pop frivolity which served to keep the upstart Lady Gaga machine chugging along at the beginning of her career."

Following its release, "LoveGame" debuted on the Billboard Hot 100 at number 96 for the week ending March 21, 2009, but fell off the chart the following week. After seven weeks it reached number ten on the Hot 100 by selling 107,000 digital downloads and becoming the week's greatest digital gainer. Two weeks later, "LoveGame" peaked at number five on the chart. It reached number-one on the Hot Dance Club Songs, and also became Gaga's third number-one on the Mainstream Top 40 chart.

It has sold 2.67 million digital downloads in the United States as of February 2019, according to Nielsen Soundscan.

In Canada, the song debuted on the Canadian Hot 100 at number 68 before its official release as a single. Its second appearance was on the chart of January 10, 2009, at number 87.

The music video of "LoveGame" was directed by Joseph Kahn and premiered on March 23, 2009, in Australia, and on August 13, 2009, in the UK on 4Music channel. The video mainly takes place in a subway station, hence several scenes are reminiscent to Michael Jackson's "Bad" music video, which was also shot in a similar location. The music video for "LoveGame" was shot back-to-back with the video for "Eh, Eh (Nothing Else I Can Say)" on the weekend of January 9, 2009, inside a warehouse at the Port of Los Angeles. Although the video was filmed in Los Angeles, it nevertheless has a New York City setting.

Gaga spoke to Whitney Pastorek of Entertainment Weekly during a "Behind the Scenes" episode of the shoot, about her inspirations for the video. She wanted to have a "giant" dance video with "LoveGame", describing it as "plastic, beautiful, gorgeous, sweaty, tar on the floor". There would be scary and dangerous looking men also in the video. Gaga had the idea of portraying herself and her co-actors as New York inhabitants taking on the role of designers, performance artists, dancers etc. She enlisted people from downtown New York as dancers, who normally would not get cast in a video.

One of the props developed for the video was a pair of sunglasses made of wire. According to Gaga, she imagined "a downtown, bad-ass kid walking down the street with his buddies, grabbing a pair of pliers, and making a pair of sunglasses out of a fence on the street". She wore them on the opening shot of the music video along with a chain link hood garment, saying that "they look so hard. It looks like I plied them right out of the fence and put them on my face".

The video starts with the heading "Streamline presents" and three men moving through Times Square. They open a manhole cover on which "Haus of Gaga" is written. Gaga is then shown naked with blue and purple paint and glitter on her body, frolicking with two men who have the words "Love" and "Fame" shaved into their heads. The scene shifts to a subway where Gaga starts singing in a grey-white leotard with a hood. She carries her characteristic disco stick and wears chain-linked glasses. The chorus starts with Gaga and her dancers progressing through the subway and dancing down a staircase. Two harlequin Great Danes, are also shown on top of the staircase.

The video shifts to a train where the second verse takes place with choreographed dance routines and Gaga wearing black and white jackets. During the intermediate music, Gaga is shown entering a ticket booth with an inspector while kissing and caressing. As the camera pans from right to left the inspector changes from a man to woman in each frame. According to Emma Hope Allwood of Dazed, in the clip Gaga wears Nazi chic fashion based on an outfit Charlotte Rampling wore in The Night Porter (1974); Allwood noted that the outfit had previously been appropriated in the videos for Madonna's "Justify My Love" (1990) and Marilyn Manson's "The Fight Song" (2001). The final scene shows Gaga doing a choreographed dance routine with her crew of backup dancers. The video comes to an end as Gaga and her dancers hold their groins, gesturing towards the camera.

The music video was censored in many countries after its release in 2009. The video faced censorship troubles in Australia where it was rated M by Network Ten for the "suggestive video footage involving bondage and sexual acts". The channel demanded an edited version of the video which would not violate censorship rules. Video Hits refused to air the video in its G- and PG-rated time slots. They cited "numerous sexual references both visually and lyrically" as the reason they could not create a child-friendly edit without bleeping the repeated hook "I wanna take a ride on your disco stick". However, Australian programs like Rage and cable networks Channel V and MTV aired the video in its original form.

The video also faced a ban from MTV Arabia citing the same reason as Australia. Since it was very rare to ban videos on MTV, head of MTV Arabia Samer al Marzouki commented, "We represent the young generation's mentality and culture so we can't play something that conflicts with that. If they can't watch something comfortably with their brother, sisters or friends then we will not play it." In the United States, VH1 and MTV played an edited version that removed the scenes showing Gaga naked, and blurred the label on a bottle of alcohol held by a dancer, but they did not change the lyrics.
