Taylor Alison Swift (born December 13, 1989) is an American singer-songwriter. Known for her biographical songwriting, artistic reinventions, and cultural impact, Swift is a leading figure in popular music and the subject of widespread public interest.

Swift signed to Big Machine Records in 2005, starting as a country singer with the albums Taylor Swift (2006) and Fearless (2008). Their singles "Teardrops on My Guitar", "Love Story", and "You Belong with Me" found crossover success on country and pop radio formats. She experimented with rock on Speak Now (2010) and electronic on Red (2012), later recalibrating her image from country to pop with the synth-pop album 1989 (2014); the ensuing media scrutiny inspired the hip-hop-imbued Reputation (2017). The albums contained the Billboard Hot 100 number-one singles "We Are Never Ever Getting Back Together", "Shake It Off", "Blank Space", "Bad Blood", and "Look What You Made Me Do".

Shifting to Republic Records in 2018, Swift released the electropop album Lover (2019) and the autobiographical documentary Miss Americana (2020), explored indie folk styles in the 2020 albums Folklore and Evermore, and subdued pop genres on Midnights (2022) and The Tortured Poets Department (2024). She re-recorded four of her albums as Taylor's Version due to an ownership dispute with Big Machine. The albums garnered the U.S. number one songs "Cardigan", "Willow", "All Too Well", "Anti-Hero", "Cruel Summer", "Is It Over Now?", and "Fortnight" in the 2020s. Her sixth concert tour, the Eras Tour (2023–2024), and its accompanying concert film are respectively the highest-grossing tour and concert film of all time. Her vast fanbase is the Swifties.

Swift is one of the world's best-selling music artists with an estimated 200 million global sales. Seven of her albums moved over one million pure sales first-week. She is the highest-grossing female touring act, the first billionaire with music as primary income, and the richest female musician ever. She has been listed amongst history's greatest artists by publications such as Rolling Stone, Billboard, and Forbes, as well as the only individual from the arts to have been named the Time Person of the Year (2023). Her accolades include 14 Grammy Awards, a Primetime Emmy Award, 40 American Music Awards, 39 Billboard Music Awards, and 30 MTV Video Music Awards; she has won the Grammy Award for Album of the Year, MTV Video Music Award for Video of the Year and the IFPI Global Recording Artist of the Year at least four times each.
