MusicXML scores for euphonium by Madonna

Madonna Louise Ciccone (; born August 16, 1958) is an American singer, songwriter, and actress. Nicknamed the "Queen of Pop", she has been recognized for her continual reinvention and versatility in music production, songwriting and visual presentation. Madonna's works, which incorporate social, political, sexual, and religious themes, have generated both controversy and critical acclaim. A cultural icon spanning both the 20th and 21st centuries, she remains one of the most "well-documented figures of the modern age" according to the Rock and Roll Hall of Fame, with a broad array of scholarly reviews, literature, and art works about her, as well as an academic mini subdiscipline devoted to her called Madonna studies.

Madonna moved to New York City in 1978 to pursue a career in modern dance. After performing as a drummer, guitarist, and vocalist in the rock bands Breakfast Club and Emmy, she rose to solo stardom with her 1983 eponymous debut studio album. Madonna followed it with a series of successful albums, including all-time bestsellers Like a Virgin (1984), True Blue (1986), and The Immaculate Collection (1990), the critically acclaimed Like a Prayer (1989), as well as Grammy Award winners Ray of Light (1998) and Confessions on a Dance Floor (2005). She has amassed a catalog of various hit songs, including "Like a Virgin", "La Isla Bonita", "Like a Prayer", "Vogue", "Take a Bow", "Frozen", "Music", "Hung Up" and "4 Minutes".

Madonna's popularity was enhanced by roles in films such as Desperately Seeking Susan (1985), Dick Tracy (1990), A League of Their Own (1992) and Evita (1996). While the lattermost won her a Golden Globe Award for Best Actress, many of her other films were not as well received. As a businesswoman, she founded the company Maverick in 1992, which included Maverick Records, one of the most successful artist-run labels in history. Madonna's other ventures include fashion brands, written works, health clubs and filmmaking. She contributes to various charities, having founded the Ray of Light Foundation in 1998 and Raising Malawi in 2006, and advocates for gender equality and LGBT rights.

With sales of over 300 million records worldwide, Madonna is the best-selling female recording artist of all time. She is the most successful solo artist in the history of the US Billboard Hot 100 chart and has achieved 44 number-one singles in between major global music markets. She became the first ever woman to accumulate US$1 billion in concert revenue, with six of her solo headlining tours having grossed over US$100 million each. Forbes has named her the world's highest-paid female musician a record 11 times across four separate decades (1980s–2010s). Madonna was inducted into the Rock and Roll Hall of Fame in 2008, her first year of eligibility. She was ranked as the greatest woman in music by VH1, and as the greatest music video artist ever by MTV and Billboard. She was also listed among Rolling Stone's greatest artists and greatest songwriters of all time.
