Taylor Alison Swift (born December 13, 1989) is an American singer-songwriter. Her narrative songwriting, which often takes inspiration from her personal life, has received widespread critical praise and media coverage.

Born in West Reading, Pennsylvania, Swift relocated to Nashville, Tennessee, in 2004 to pursue a career in country music. She broke into the country music scene with her eponymous debut studio album in 2006, which included the singles "Teardrops on My Guitar" and "Our Song". Swift rose to mainstream prominence with her second studio album, Fearless (2008), a country pop record with crossover appeal. Aided by the top-five singles "Love Story" and "You Belong with Me", Fearless was certified Diamond by the Recording Industry Association of America (RIAA). Swift's third studio album, Speak Now (2010), blended country pop with elements of rock and featured the top-ten singles "Mine" and "Back to December".

Drawing inspiration from various pop, rock, and electronic genres, Swift's fourth studio album Red (2012) saw her transcending her country roots. She officially moved to pop with her synth-pop fifth studio album, 1989 (2014), and expanded the electropop sound on her next two studio albums, Reputation (2017) and Lover (2019), which respectively embraced urban and retro styles. The four albums spawned a string of international top-five singles, including "We Are Never Ever Getting Back Together", "I Knew You Were Trouble", "Shake It Off", "Blank Space", "Bad Blood", "Look What You Made Me Do", "Me!" and "You Need to Calm Down". Swift experimented with folk and alternative rock on her eighth and ninth studio albums, Folklore and Evermore (both 2020), whose lead singles "Cardigan" and "Willow" topped charts around the world.

With sales of over 200 million records worldwide, Swift is one of the best-selling music artists. Her accolades include 11 Grammy Awards (including three Album of the Year wins), an Emmy Award, 28 Guinness World Records, 32 American Music Awards (the most wins by an artist), and 23 Billboard Music Awards (the most wins by a woman). She ranked eighth on Billboard's Greatest of All Time Artists Chart (2019) and was listed on Rolling Stone's 100 Greatest Songwriters of All Time (2015). Swift has been included in various power rankings, such as Time's annual list of the 100 most influential people in the world (2010, 2015 and 2019) and Forbes Celebrity 100 (placing first in 2016 and 2019). She was named Woman of the Decade (2010s) by Billboard and Artist of the Decade (2010s) by the American Music Awards.
