Dangerously in Love is the debut solo studio album by American singer and songwriter Beyoncé. It was released on June 23, 2003, by Columbia Records and Music World Entertainment.

During the recording of Destiny's Child's third studio album Survivor (2001), the group announced that each member would produce solo albums. Recording sessions for Dangerously in Love took place from March 2002 to March 2003 at various recording studios, during the group's hiatus. As the executive producer of the album, Beyoncé took a wider role in its production, co-writing a majority of the songs, choosing which ones to produce and sharing ideas on mixing and mastering. Although she remained discreet about her interpretation of the album's songs, their underlying meanings were attributed by media outlets as an allusion to her intimate relationship with rapper, Jay-Z. Musically, the album is a mixture of uptempo tracks and ballads, all of which are primarily R&B songs, while also incorporating elements of soul, hip hop and Arabic music.

Upon its release, Dangerously in Love received generally positive reviews from music critics, many of whom praised Beyoncé's "artistic leap". An international commercial success, the album debuted atop the US Billboard 200, selling 317,000 copies in its first week and earning Beyoncé the highest debut-week sales among Destiny's Child members' solo albums. At the 46th Annual Grammy Awards (2004), the album and its songs won five awards, including Best Contemporary R&B Album; Beyoncé consequently tied with Lauryn Hill, Alicia Keys and Norah Jones for the record of most Grammy Awards won by a woman at a single ceremony. Dangerously in Love has been certified sextuple platinum by the Recording Industry Association of America (RIAA) and, as of 2011, has sold over 11 million copies worldwide, making it one of the best-selling albums of the 21st century.

Dangerously in Love produced four singles. "Crazy in Love" spent eight consecutive weeks atop the US Billboard Hot 100, reaching the top ten almost everywhere it charted and winning two Grammy Awards. "Baby Boy" replicated the international commercial success of "Crazy in Love" while outlasting it atop the Billboard Hot 100 by one week. "Me, Myself and I" peaked at number four on the Billboard Hot 100 while attaining lower peaks than its predecessors internationally. "Naughty Girl" peaked at number three on the Billboard Hot 100 and within the top ten in several additional countries. Beyoncé promoted the album via numerous live performances and two concert tours—Dangerously in Love Tour (2003) and Verizon Ladies First Tour (2004), the latter of which was co-headlined with Alicia Keys and Missy Elliott, while the former produced the live album Live at Wembley (2004).
