Born in Jakarta, she began performing at the age of seven and recorded a children's album two years later. She rose to fame in 1989 as a teenage rock star and by 1993 she had released five Indonesian-language studio albums. Rolling Stone listed her single "Mimpi" as one of the 150 Greatest Indonesian Songs of All Time.

Anggun left Indonesia for England in 1994 to pursue an international career. She later moved to France and recorded her first international album, Snow on the Sahara (1997). It was released in 33 countries by Sony Music and sold more than one million copies worldwide. Since then, Anggun has released another six studio albums—in English and French—and a soundtrack album to the Danish film Open Hearts (2002). Her singles "Snow on the Sahara", "What We Remember", "The Good Is Back", and "Perfect World" entered the Billboard charts in the United States while "In Your Mind", "Saviour" and "I'll Be Alright" charted on the Billboard European Hot 100 Singles. She represented France in the Eurovision Song Contest 2012, with the song "Echo (You and I)".

Anggun served as a judge on various TV shows across Asia and Europe, including Asia's Got Talent (2015–2019), as well as the Indonesian versions of The X Factor (2013) and The Voice (2018); the French version of Masked Singer (2019–2022); and the Belgian version of Starmaker (2023). Her acting works include supporting roles in films Coup de foudre à Bangkok (2020) and Levitating (2026), as well as American series Reacher (2026).

Anggun is one of the best-selling Asian artists outside Asia, with her releases being certified gold and platinum in some European countries. She is the first Indonesian artist to have success in European and American record charts. She has received accolades for her achievements, including the Chevalier des Arts et Lettres from the Government of France, the World Music Award for World's Best-Selling Indonesian Artist, and the Asian Television Award for Outstanding Contribution to Asian Television Performing Arts. She became the first woman from Indonesia to be immortalized in wax by Madame Tussauds.

Anggun was born in Jakarta on 29 April 1974. She is the second child of Darto Singo, a Javanese writer, and Dien Herdina, a housewife from the Yogyakarta royal family. Her full name means "grace born of a dream". Despite being a Muslim, Anggun was sent to a Catholic school to receive a better elementary education. At the age of seven, Anggun began receiving daily strict instructions in singing and was given homework to write poems with the melodies that could become a song, aimed at triggering her songwriting skills, by her father. Even though her father was not a singer, he guided her to improve her vocal skill by following the instructions in a vocal practicing book written by Bina Vokalia vocal coach Pranadjaja. Her mother began serving as her manager. At the age of nine, Anggun started writing her own songs and recorded her debut album, which featured covers of songs by Indonesian country singer Ritta Rubby Hartland, titled Kepada Alam dan Pencintanya (1983). However, the album was not published until she gained recognition in the early 1990s.

In adolescence, Anggun was influenced by Western rock music and she began to choose her career as a rock singer. In 1986, she met Ian Antono, the guitarist and music producer of God Bless, and released her first commercial studio album, Dunia Aku Punya; however, it did not achieve commercial success. She rose to fame three years later, with the single "Mimpi"; it was ranked by Rolling Stone Indonesia as one of the 150 Greatest Indonesian Songs of All Time. In the early 1990s she released hit singles such as "Tua Tua Keladi", "Laba Laba", and "Takut". She recorded the studio albums Anak Putih Abu Abu (1991) and Nocturno (1992). The former earned her the Most Popular Indonesian Artist 1990–1991 award by Popular Magazine.

In 1992, Anggun began a relationship with Michel Georgea, a French engineer. They married, despite a rumoured objection by Anggun's family on the grounds that Anggun was too young. Georgea later became Anggun's manager. The following year, Anggun became the youngest Indonesian singer to found her own record company, Bali Cipta Records, taking creative control over her work. She produced her fourth (fifth overall) Indonesian studio album, Anggun C. Sasmi... Lah!!! (1993), which yielded the hit song "Kembalilah Kasih (Kita Harus Bicara)". By age nineteen, she had sold over four million albums in Indonesia. She was dissatisfied with her success in her country and began considering an international music career.

In 1994, Anggun released Yang Hilang, a greatest hits album of her Indonesian popular songs. She later sold her record company to fund her move to Europe, and moved to London. In a 2006 interview, Anggun admitted to "culture shock" and financial problems while trying to start her new life in Europe.
