"Crazy in Love" is a song recorded by American singer and songwriter Beyoncé for her debut solo studio album Dangerously in Love (2003). It features a rap verse and ad-libs from Jay-Z, her now-husband. Both artists wrote and composed the song in collaboration with Rich Harrison and Eugene Record; the former also produced it with Beyoncé. Using samples from the Chi-Lites's 1970 song "Are You My Woman (Tell Me So)", "Crazy in Love" is a pop, hip hop and R&B love song that incorporates elements of soul, and 1970s-style funk music. Its lyrics describe a romantic obsession causing the protagonist to act out of character. The song was released as the lead single from Dangerously in Love on May 18, 2003, by Columbia Records.

"Crazy in Love" was a number-one hit in the United States and United Kingdom, and reached the top ten in various other countries worldwide. The song was universally acclaimed; music critics praised the hook, Jay-Z's contribution, and Beyoncé's assertive vocals. VH1 declared it the greatest song of the 2000s decade, while Rolling Stone ranked it at number 16 on their list of the 500 greatest songs of all time in 2021, and in 2018, declared the song the greatest of the 21st century so far. At the 46th Annual Grammy Awards (2004), "Crazy in Love" won Grammy Awards for Best R&B Song and Best Rap/Sung Collaboration.

The song's accompanying music video features Beyoncé in various dance sequences. It won three awards at the 2003 MTV Video Music Awards, and its director, Jake Nava, won the Music Video Production Association award for Best R&B Video in 2004. Since 2003, "Crazy in Love" has been a staple in Beyoncé's live performances and concert tours. The American Society of Composers, Authors and Publishers (ASCAP) recognized "Crazy in Love" as one of the most performed songs of 2004. Artists including David Byrne have covered the song, and it has been used in various television shows and other media.

By July 2002, Beyoncé had already recorded several songs which would appear on Dangerously in Love. Columbia Records planned to release the album in October 2002; however, the release was postponed several times to capitalize on the success of American rapper Nelly's 2002 single "Dilemma," which features Beyoncé's former Destiny's Child colleague Kelly Rowland. These delays allowed Beyoncé to record more songs for the album.

Before meeting Beyoncé, Rich Harrison had conceptualized the beat of the song. He had sampled the hook's instrumentation from the 1970 song "Are You My Woman? (Tell Me So)," which had originally been written and composed by Eugene Record, frontman of the Chicago-based vocal group the Chi-Lites. When Harrison first played the beat to his friends, they could not "dig it," and this made him realize that he had conceived something special, which people would appreciate better after hearing the whole record. Thus Harrison decided not to market the selection, and instead, he waited for the right artist to record it: "I had it in the chamber, I had not really shopped it much, because sometimes you do not want to come out of the bag before it's right. People do not really get it and you will leave them with a foul taste in their mouth."

Harrison was pleasantly surprised when he got a call from Beyoncé, who was working on one of the most anticipated albums of the year. However, things did not turn up according to his plans the following day, as he was late and was still suffering the effects of a hangover. When Harrison played the sample to Beyoncé in the studio, the singer initially had doubts about the "sound so full of blaring fanfare;" it seemed too retro and according to her, no one used horn riffs in the 21st century. Nevertheless, Beyoncé accepted the sample, much to Harrison's delight, and gave him two hours to write and compose the song while she went out.

Harrison confessed that it was not easy for him to come up with the lyrics to "Crazy in Love" in that length of time. But two hours later, he had written the verses and the hook, in spite of being hung over. Harrison had also made provision for a backing track; he played all the instruments on the track. The bridge was written by Beyoncé, who was inspired by looking at herself in the mirror; as she was not wearing matching clothes and her hair was untidy, she kept saying, "I'm looking so crazy right now." Harrison sang back to her and said, "That's the hook." It also inspired the title of the song. After that Beyoncé had filled up the middle eight, she came up with the catchphrase – "Uh-oh, uh-oh, you know" – alongside Harrison.

Featured artist Jay-Z became involved late in the song's production. Around 3 am, he came to the studio and recorded a rap verse, which he improvised in about ten minutes. The recording of "Crazy in Love" took place nearly three months following the meeting of Beyoncé with Harrison.

"Crazy in Love" is performed in the key of D. It incorporates influences of 1970s-style funk, hip hop, and soul. As commented by Robert Webb of The Independent, the old soul influences in the song seem to have been derived from the horn hook, which samples the 1970 song "Are You My Woman? (Tell Me So)." Having a "go-go vibe", "Crazy in Love" is built on a hip hop beat. Beyoncé told The Sunday Herald that the beat is "so hard that it makes your heart hurt." The song's tempo is a moderate 100 beats per minute, in common time. Beyoncé's vocal range spans around one and a half octaves in the song, from the low note of B♭₃ to the high note of F₅. "Crazy in Love" uses two major chords, B♭ and G, a minor third apart. One of the main vocal riffs uses the traditional cowbell rhythm often found in samba music. Lisa Verrico of The Times magazine, wrote that "Crazy in Love" makes use of big drums and bits of brass.

According to Natalie Nichols of the Los Angeles Times, the lyrics of "Crazy in Love" reference a state of romantic obsession. Beyoncé said that the song talks "about how, when you are falling in love, you do things that are out of character and you do not really care because you are just open." Anthony DeCurtis of Rolling Stone wrote that "Crazy in Love" has "such a cauldron of energy," that Beyoncé sounds "loose and sexy," gripped by emotions she "can neither understand nor control." The lyrics are composed in the traditional verse-chorus form. Jay Z opens the song with a brief spoken verse-rap, containing the lyrics: "Yes! So crazy right now. Most incredibly, it's your girl, B. It's your boy, Young. You ready?" After Beyoncé delivers the "uh-oh, uh-oh" catchphrase, Jay Z continues the monologue. Beyoncé begins the first verse, followed with the whistle-backed chorus. She repeats the "uh-oh, uh-oh" phrase, leading to the second verse. The chorus follows, giving way to the second verse-rap which contains the lyrics: "Jay Z in the range, crazy and deranged [...] I been iller than chain smokers, how you think I got the name 'Hova', I been real and the game's over". The song continues to the bridge, singing: "I'm not myself, lately I'm foolish, I don't do this, / I've been playing myself, baby, I don't care / 'Cuz your love's got the best of me, / And baby, you're making a fool of me, / You got me sprung and I don't care who sees." She then sings the chorus again and the song fades out with the horns.

"Crazy in Love" was first released for digital download via iTunes Store in the United States on May 14, 2003. It was then sent to rhythmic contemporary, contemporary hit radio, and urban contemporary radio stations in the United States on the week of May 18, 2003. In the United Kingdom, it was released for digital download via iTunes Store on May 20, 2003.

The song was released as a CD single in Ireland and Switzerland, and as a digital EP in Germany on June 20, 2003. "Crazy in Love" was released as a maxi single in Germany on June 30, 2003, and in Australia on July 7, 2003. The song was issued as a CD single in the United Kingdom on June 30, 2003.

"Crazy in Love" was acclaimed by contemporary music critics, who complimented the horn lines and the guest appearance of Jay-Z. Many of them called it the Summer Anthem of 2003. Tim Sendra of AllMusic described the song as a "stunning pop masterpiece", while Stephen Thomas Erlewine of the same website called it "deliriously catchy". Darryl Sterdan of Jam! noted the "Crazy in Love" is "instantly addictive horn lines". Anthony DeCurtis of Rolling Stone wrote: "'Crazy in Love' ... roars out of the speakers on the strength of a propulsive horn sample and the charged presence of her pal, Jay-Z." Ben Ratliff of Blender magazine called the song an "itchy [and] eager-to-please" one. Marc Anthony Neal of PopMatters called the "uh-oh, uh-oh" phrase catchy. MTV News considered "Crazy in Love" to be the "proudest moment" of Dangerously in Love. Similarly, Allison Stewart of The Washington Post called it the best song on the album, praising its instrumentation, harmonies, and the rap verse of Jay Z. This was echoed by Kelefa Sanneh of The New York Times who wrote that "Crazy in Love" is the best one on the album thanks to its "simplicity, irresistible combination of triumphant horns and a wicked hip-hop beat". She added that "[Beyoncé's] vocals – as deft and accurate as ever – convey none of the giddy rush that the lyrics describe." Likewise, Sal Cinquemani of Slant Magazine wrote the lyrical arrangement, the music structure and the guest vocals by Jay Z all contributed in making "Crazy in Love" a wonderful resume for Beyoncé.

Rob Fitzpatrick of NME called "Crazy in Love" a "head-nodding [and] body-rocking funk-soul genius" and wrote that it is "a 100 per cent, stone-cold, dead-cert classic". He complimented Beyoncé's vocals, describing them as "genuinely, hip-grindingly fruity". Los Angeles Times writer Natalie Nichols noted that "sexy dance tunes as the vintage funk-flavored 'Crazy in Love'" made Dangerously in Love a great album. Neil Drumming of Entertainment Weekly wrote that the song has a "fresh sound". Spence D. of IGN Music wrote that Beyoncé rides the "infectious rhythm" with grace and mid-range seductively. He added, "As [it] can be expected, the track bumps when Jay drops his distinctive uptown flavor. While other rap-meet-R&B tracks often fall flat, this one works well as Beyoncé and Jay's verbals play nicely against one another." Lisa Verrico of The Times wrote that Jay Z performed a "decent rap", however, "Beyoncé and the beats save the day" and that "Crazy in Love" was a departure for Beyoncé from Destiny's Child.

"Crazy in Love" was a commercial success in the United States, debuting at number fifty-eight on the Billboard Hot 100.

The music video of "Crazy in Love", released in May 2003, was directed by Jake Nava and filmed in downtown Los Angeles. In MTV Making of the Video 2003 documentary, Beyoncé described the video's conception: "[It] celebrates the evolution of a woman. It is about a girl who is at the point of a relationship. She realizes that she is in love, she is doing stuff she would not normally do but she does not care. It does not matter she is just crazy in love."

The opening sequence of the video features Jay-Z as a passenger in a car speeding along Mission Road in Los Angeles, where he encounters Beyoncé, standing in the middle of the road, at the Fourth Street bridge. Beyoncé performs in various dance sequences, beginning with her wearing a white tank top, denim blue shorts, and red high-heels. She performs an elaborate solo dance on a riser. The scene shifts to a gold set with a mock photo shoot, before moving into a scene with dancers detailing Beyoncé and dancing against a wall while wearing caps and full length pants. Jay Z appears and ignites a line of petrol leading to a car parked under the bridge, which explodes in flames. Jay Z performs his rap in front of the burning car, and Beyoncé dances beside him, wearing an exotic silk print over a fur coat, before kicking the valve off a fire hydrant. She continues to dance while the water is flying everywhere. The video ends with Beyoncé and her dancers wearing vibrant Versace dresses in front of a large fan. Their outfits contrast with the neutral colors of the background, the video. Carmit Bachar, then a member of The Pussycat Dolls, is one of the dancers.

The music video received acclaim by music critics. Cynthia Fuchs, writing for PopMatters commented that the photo shoot scene uses the routine used by Jennifer Lopez in the video for "Jenny from the Block" (2002) with hot lights, scary makeup, and inclusion of many shots of legs. She wrote that: "Beyoncé's body becomes its undeniable emblem." Tom Moon of The Philadelphia Inquirer wrote that Beyoncé "shakes every inch of her famously photogenic goddess frame."

The song is also recognized as the Best Selling Mobile Ringtone in the United Kingdom for 2003 In 2014, The Guardian writer Michael Cragg included the clip for "Crazy in Love" in his list of the ten best music videos by Beyoncé. He offered high praise for it, saying "Aware of how much of a statement the song was, the video is a checklist of icon-making visuals, from the locations... the dance moves... to the part where she makes bubble blowing look like the sexiest thing a human could do."

The music video on YouTube has received over 820 million views as of October 2024.

She climbed a staircase where her all-female band and three backup singers were positioned. The staircase moved forward in two places; top part moved while the bottom poked out more. At the top of her staircase, she removed her train and returned to the main stage. Her backup singers followed and danced with Beyoncé. After "Crazy in Love", Beyoncé performed a short rendition of Gnarls Barkley's "Crazy" (2006), singing: "Who do you, who do you think you are? / Ha, ha, ha, bless your soul."

Shaheem Reid of MTV News wrote: "There are few (very few) ladies out there who can really sing, a lot who can dance, a lot more who look good — but really no other who can combine all three and add iconic star power like Miss Beyoncé, arguably the best all-around stage performer in the game right now." Jon Pareles of The New York Times wrote: "Beyoncé needs no distractions from her singing, which can be airy or brassy, tearful or vicious, rapid-fire with staccato syllables or sustained in curlicued melismas. But she was in constant motion, strutting in costumes (most of them silvery), from miniskirts to formal dresses, flesh-toned bodysuit to bikini to negligee." Frank Scheck of The Hollywood Reporter wrote: "Her performance of 'Crazy in Love' featured some surprising arrangements that gave the material freshness".

"Crazy in Love" has various remixes, including the Rockwilder remix, Maurice Joshua's Nu Soul remix, and Juniors World remix. These versions appeared on the single releases of "Crazy in Love" under an alternative spelling, "Krazy in Luv". The Rockwilder remix slows down the beat and makes the song deeper and funkier with chopped up horn samples and sparkling synth textures from sampling Don't Stop the Music by Yarbrough and Peoples. Maurice's Nu Soul Remix speeds up the beat, taking it from hip-hop to house territory. A version of the song included on Asian special edition of Dangerously in Love features a rap in Mandarin Chinese performed by American-Taiwanese singer Vanness Wu, instead of Jay Z's performance.

"Crazy in Love" was re-recorded by Beyoncé for the film Fifty Shades of Grey (2015) and used for its trailer, which was released on July 24, 2014. The slowed-down version was produced by Boots with violin arrangements by Margot, both of whom worked on Beyoncé's self-titled fifth studio album (2013), and, unlike the original, doesn't feature Jay-Z. Margot said: "It inspires me to work on other artists' songs [because] it pushes my boundaries in a direction that I wouldn't necessarily come up with. Obviously I know how 'Crazy in Love' goes, but I knew there was the possibility her vocals would be different. It's almost more vulnerable and beautiful this way, because you do do crazy things when you fall in love. To hear the mood reversed and flipped makes it even more powerful."

The track was then officially released through iTunes Store on February 10, 2015. The single cover artwork uses the same image used in the original cover, but in black and white. The rendition was performed for the first time during the 2015 Budweiser Made in America Festival on September 5, 2015, and was included on the setlist of The Formation World Tour (2016), alongside the original version.
