Beyoncé Giselle Knowles-Carter ( bee-ON-say; born September 4, 1981) is an American singer, songwriter, actress, and businesswoman. Known for her vocal ability, artistic reinventions, and live performances, she is widely regarded as one of the most culturally significant figures of the 21st century. Credited with shaping popular music, Beyoncé is often deemed one of the greatest entertainers of all time.

Beyoncé rose to fame in the late 1990s as the lead singer of Destiny's Child, one of the best-selling girl groups of all time. Her debut solo album, Dangerously in Love (2003), became one of the best-selling albums of the 21st century. After Destiny's Child disbanded in 2005, Beyoncé released the funk-imbued B'Day (2006) and starred in the drama film Dreamgirls (2006). Her marriage to rapper Jay-Z and portrayal of Etta James in the biopic Cadillac Records (2008) influenced her pop-oriented double album I Am... Sasha Fierce (2008). Through the 2000s, Beyoncé garnered the US Billboard Hot 100 number-one singles "Crazy in Love", "Baby Boy", "Check on It", "Irreplaceable", and "Single Ladies (Put a Ring on It)".

After forming the management company Parkwood Entertainment, Beyoncé embraced traditional R&B and soul on 4 (2011). The electronic-influenced Beyoncé (2013) popularized surprise and visual albums, inspiring the setting of Friday as Global Release Day, while the eclectic Lemonade (2016) sparked sociopolitical discourse and was the best-selling album of 2016. Her ongoing trilogy project—consisting of the queer-inspired dance album Renaissance (2022) and the Americana-rooted Cowboy Carter (2024)—has highlighted the overlooked contributions of Black pioneers to American musical and cultural history, spawning the US number-one singles "Break My Soul" and "Texas Hold 'Em".

Beyoncé is one of the best-selling music artists of all time, with estimated sales of over 200 million records. She is the most RIAA-certified female artist and the only woman whose first eight studio albums each debuted atop the US Billboard 200. One of the most-awarded artists in popular music, she is the recipient of 35 Grammy Awards—the most of any act—a Primetime Emmy Award, and a Peabody Award. Beyoncé is the most-awarded artist of the BET Awards (36), MTV Video Music Awards (30), NAACP Image Awards (32), and Soul Train Music Awards (25). The first woman to headline an all-stadium tour, she is the highest-grossing Black live act of all time.
