Beyoncé Giselle Knowles ( born September 4, 1981), often known simply as Beyoncé, is an American R&B recording artist, actress and fashion designer. Born and raised in Houston, Texas, she enrolled in various performing arts schools and was first exposed to singing and dancing competitions as a child. Knowles rose to fame in the late 1990s as the lead singer of the R&B girl group Destiny's Child, one of the world's best-selling girl groups of all time.

During the hiatus of Destiny's Child, Knowles released her debut solo album Dangerously in Love in 2003, which spawned the number-one hits "Crazy in Love" and "Baby Boy" and became one of the most successful albums of that year, earning her a then record-tying five Grammy Awards. Following the group's disbandment in 2005, Knowles released her second solo album, B'Day in 2006. It debuted at number one on the Billboard 200 and included the hits "Irreplaceable" and "Beautiful Liar". Her third solo album I Am... Sasha Fierce was released in 2008, and included the anthemic "Single Ladies (Put a Ring on It)". The album earned Knowles six Grammys at the 52nd Grammy Awards, breaking the record for most Grammy Awards won by a female artist in one night.

Apart from her work in music, Knowles has also launched a career in acting. In 2001, she made her debut in the musical film Carmen: A Hip Hopera, prior to appearing in major films, including Dreamgirls (2006), which earned her two Golden Globe nominations, and Cadillac Records (2008). In 2004, Knowles and her mother introduced their family's fashion line, House of Deréon; Knowles has also endorsed brands such as Pepsi, Tommy Hilfiger, Armani and L'Oréal. In June 2010, Knowles was ranked second on Forbes list of the 100 Most Powerful and Influential celebrities in the world, and first on its list of the Most Powerful and Influential musicians in the world.

Knowles has earned numerous awards and accolades. She is one of the most honored artists by the Grammys, and third among female artists, with a total of 16 Grammy Awards – 13 as a solo artist and 3 as a member of Destiny's Child. Knowles was ranked the 4th Artist of the 2000s decade by Billboard and was listed the most successful female artist of the decade, as well as the top radio artist of the decade. The Recording Industry Association of America (RIAA), also listed Knowles as the top certified artist of the decade.

As of September 2009, she has sold 75 million records worldwide, making her one of the best-selling music artists of all time.

In January 2010, Knowles was interviewed by USA Today and announced plans to take a break from music in 2010. She stated, "it's definitely time to take a break, to recharge my batteries. ... I'd like to take about six months and not go into the studio. I need to just live life, to be inspired by things again." During this time, a 60 Minutes segment aired, revealing Knowles was homeschooled as a child and prays before every performance. In February 2010, Lady Gaga's song "Telephone" was released featuring Knowles. The single reached number one on the US Pop Songs chart, thus becoming the sixth number-one on the chart for both Knowles and Lady Gaga. With this, they both tied with Mariah Carey for most number-ones since the Nielsen BDS-based Top 40 airplay chart launched in 1992. "Telephone" received a Grammy nomination for Best Pop Collaboration with Vocals at the 53rd Grammy Awards.

In June 2010, Forbes placed Knowles at number three on its list of "Top-Earning Musicians" with $87 million in grosses for her 93-date world tour, deals with Nintendo and L'Oréal and her House of Deréon clothing line.[107] This made her the world's best paid female artist for this span of time. In October 2010, Forbes recognized Knowles as the ninth "Most Powerful Woman in the World". She also ranked at ninth place on Forbes' list of "Hollywood's 20 Highest Earners of 2010", becoming the only artist to break the top ten.

In January 2011, it was made known that Knowles would appear in a remake of A Star Is Born, to be directed and produced by Clint Eastwood for Warner Bros.. The remake will be the fourth telling of the A Star Is Born tale, the most memorable in recent years being the 1976 version with Barbra Streisand and Kris Kristofferson. In February 2011, documents obtained by the WikiLeaks website revealed that Knowles along with Usher, Mariah Carey and Nelly Furtado had received as much as $1 million to perform for family members of Libyan politician Muammar Gaddafi. Rolling Stone magazine reported that the music industry was urging them to return the money they earned for the concerts. On March 2, 2011, a spokesperson for Knowles told The Huffington Post that she had donated the money to the Clinton Bush Haiti Fund, established to aid the victims of the 2010 Haiti earthquake. On March 28, 2011, it was announced that Knowles' father and longtime manager Mathew Knowles would no longer manage her. Knowles' publicist released a statement to The Associated Press revealing that Knowles and her father have split "on a business level." She now manages herself and has hired her own team. In June 2011, Forbes placed Knowles eighth on its list of "Best-Paid Celebrities Under 30" for earning $35 million between the months of May 2010 and 2011. Forbes noted that was low placement for Knowles was due to the fact she spent most of the past year off the road and recording her then upcoming fourth studio album.

Knowles' fourth studio album 4 will be released on June 24, 2011. The album was inspired by several musicians, including Fela Kuti, The Stylistics, Lauryn Hill, Stevie Wonder and Michael Jackson. Its lead single, "Run the World (Girls)" peaked at number twenty-nine on the Billboard Hot 100, and became Knowles' lowest charting lead single as a solo artist. The album's second single, "Best Thing I Never Had", was released on June 1, 2011. Knowles headlined at the 2011 Glastonbury Festival, performing a 90-minute set on the last day of the festival on June 26, 2011. She will also be performing at the Oxegen Festival in Ireland, and the T in the Park Festival in Scotland during July 2011.

Knowles' music is generally contemporary R&B, but she also incorporates pop, funk, hip hop, and soul into her songs. While she almost exclusively releases English songs, Knowles recorded several Spanish records for Irreemplazable and the re-release of B'Day. Prior to recording the Spanish titles on the album's re-release, Knowles was coached phonetically by American record producer, Rudy Perez.

Since Destiny's Child, Knowles has artistically been involved in her career. She received co-writing credits for most of the songs recorded by the group, as well as her solo efforts. Known for writing personally driven and female-empowerment themed compositions, Knowles has stated that having Jay-Z in her life has changed a few of her thoughts about how men and women relate to one another, which helped her transition from writing songs such as "Independent Women" and "Survivor" to man-tending anthems such as, "Cater 2 U" in which she sings about bringing him slippers and drawing his bath. Some of her songs are autobiographical, which she has admitted are taken from personal experiences, as well as her friends'. Knowles has also received co-producing credits for most of the records in which she has been involved, especially during her solo efforts. However, she does not formulate beats herself, but typically comes up with melodies and ideas during production, sharing them with producers. Knowles was recognized as a songwriter during the run of Destiny's Child in the 1990s and early to mid-2000s. She won the Pop Songwriter of the Year award at the 2001 American Society of Composers, Authors, and Publishers Pop Music Awards, becoming the first African-American female and second female songwriter of all time to accomplish the feat. Knowles received songwriting credits in a single year for co-writing "Irreplaceable", "Grillz" and "Check on It", all of which reached number one on the Hot 100, the only woman to have written three songs which went to number-one in the same year since Carole King did it in 1971 and Mariah Carey in 1991. In terms of credits, she is tied with Diane Warren at third with nine number-one singles.

Knowles possesses a mezzo-soprano vocal range that spans more than three octaves. She has often been identified as the centerpiece of Destiny's Child. Jon Pareles of The New York Times commented that she has the voice that defines the group, writing that her voice is "velvety yet tart, with an insistent flutter and reserves of soul belting". Other critics praise her range and power. In reviewing her second album B'Day, Jody Rosen of Entertainment Weekly wrote "Beyoncé Knowles is a storm system disguised as a singer. On her second solo album, B'Day, the songs arrive in huge gusts of rhythm and emotion, with Beyoncé's voice rippling over clattery beats; you'd have to search far and wide—perhaps in the halls of the Metropolitan Opera – to find a vocalist who sings with more sheer force...No one—not R. Kelly, not Usher, to say nothing of her rival pop divas—can match Beyoncé's genius for dragging her vocal lines against a hip-hop beat." Chris Richards of The Washington Post wrote, "Even when she's coasting, she soars above her imitators. It's all in her voice—a superhuman instrument capable of punctuating any beat with goose-bump-inducing whispers or full-bore diva-roars. Smitten, scorned, amorous, antagonistic—Beyoncé sings from all of these vantage points with undeniable virtuosity." Cove magazine ranked Knowles seventh on their list of "The 100 Outstanding Pop Vocalists", giving her 48 out of 50 points based on several criteria ranging from her vocal ability to range to harmony.

Knowles has often been criticized for oversinging. A prominent employer of melisma, she earns frequent comparison to such artists as Mariah Carey, whose vocal embellishments have been known to detract from the melody of their songs. Editors from Eye Weekly wrote, "There’s no question that Beyoncé is one of the best singers in pop, maybe one of the best alive...[However] as judicious as her singing can be, the effect in sum is still like being hit in the head with a fist in a velvet glove."

Throughout her career, Knowles has received numerous awards and achievements. In 2007, she became the first female artist to be awarded the International Artist Award at the American Music Awards. At the 2008 World Music Awards, Knowles was honored the legend award for Outstanding Contribution to the Arts. She was also honored with a Billboard Millennium Award at the 2011 Billboard Music Awards, for recognizing her career achievements and influence in the music industry. Knowles is one of the most honored artists by the Grammys, and third among female artists, with a total of 16 Grammy Awards – 13 as a solo artist and 3 as a member of Destiny's Child. Her debut studio album, Dangerously in Love, was listed as one of the top 200 definitive albums in music history by the Rock & Roll Hall of Fame.

In December 2009, Billboard listed Knowles as the most successful female artist and the top radio artist of the 2000s decade. Billboard also ranked her the 4th artist of the decade, and the 15th top 25 R&B/Hip-Hop artist of the past 25 years (1985–2010). BET also recognized Knowles as the second most influential artist of the decade. In February 2010, the Recording Industry Association of America (RIAA) listed Knowles as the top certified artist of the decade, with a total of 64 certifications, including albums, digital songs, master ringtones and music videos. In August 2010, VH1 listed her at number 52 on its list of the 100 Greatest Artists of All Time. As of September 2009, Knowles has sold 75 million records worldwide as a solo artist, making her one of the best-selling music artists of all time.
