Alecia Beth Moore-Hart (née Moore; born September 8, 1979), known professionally as Pink (stylized as P!NK, and on music streaming services as P!nk), is an American singer and songwriter. She is known for her acrobatic stage presence and activism.

At the age of 15, Pink formed the short-lived girl group Choice, who signed with LaFace Records in 1995, although they disbanded without any major releases. Her first solo studio album, Can't Take Me Home (2000), was released to commercial success and received double platinum certification by the Recording Industry Association of America (RIAA). Produced by label boss Babyface and influenced by contemporary R&B, the album spawned two US Billboard Hot 100-top ten singles: "There You Go" and "Most Girls". Pink gained further recognition for her 2001 collaborative single "Lady Marmalade" from the soundtrack of Moulin Rouge!, which peaked atop 13 international charts, including the US, and earned her first Grammy Award for Best Pop Collaboration with Vocals. Pink shifted to pop rock with her second studio album, Missundaztood (2001), which sold over 13 million copies worldwide and yielded three top ten singles: "Get the Party Started", "Don't Let Me Get Me", and "Just Like a Pill".

Pink's third studio album, Try This (2003), sold significantly less than her second studio album, but earned her second Grammy for Best Female Rock Performance. Her fourth and fifth studio albums, I'm Not Dead (2006) and Funhouse (2008), saw a commercial rebound and spawned the top-ten singles "Who Knew" and "U + Ur Hand", as well as the US number-one single "So What". She scored her third and fourth US number-ones with "Raise Your Glass", as well as "Just Give Me a Reason" from her sixth album, The Truth About Love (2012), which became her first to top the US Billboard 200. In 2014, Pink formed the collaborative folk duo You+Me with Canadian musician Dallas Green, who released the album Rose Ave. in October of that year. Her following albums, Beautiful Trauma (2017) and Hurts 2B Human (2019), saw continued success and debuted at No. 1 on the Billboard 200 chart, with the former becoming the third best-selling album of that year worldwide. Her ninth and latest studio album, Trustfall (2023), peaked at number two on the chart.

Pink has sold over 135 million records worldwide (60 million albums and 75 million singles), making her one of the world's best-selling music artists. Pink is also the most-played female solo artist in the United Kingdom during the 21st century, while Billboard named Pink the Pop Songs Artist of the 2000s Decade. Her accolades include three Grammy Awards, two Brit Awards (including Outstanding Contribution to Music), a Daytime Emmy Award and seven MTV Video Music Awards (including the Michael Jackson Video Vanguard Award) and two MTV Europe Music Awards. At the 63rd annual BMI Pop Awards, she received the BMI President's Award for "her outstanding achievement in songwriting and global impact on pop culture and the entertainment industry", and she was honored with the People's Champion Award, the iHeartRadio Music Award Icon Award. Billboard also named Pink the 2013 Woman of the Year at the Billboard Women in Music and honored her with the Billboard Icon Award and the Billboard Legend of Live. VH1 ranked her 10th on its list of the 100 Greatest Women in Music.

Alecia Beth Moore was born on September 8, 1979, in Doylestown, Pennsylvania, to emergency room nurse Judith Moore (née Kugel) and insurance salesman James Moore. She has described herself as an "Irish-German-Lithuanian Jew", and her mother is Jewish. Although a healthy baby, she developed asthma that plagued her through her early years. When Pink was a toddler, her parents began having marital problems; they divorced before she was 10.

Pink was trained as a competitive gymnast between the ages 4 and 12. She attended Central Bucks High School West. In high school, Pink joined her first band, Middleground, but it disbanded upon losing a Battle of the Bands competition. As a teenager, she wrote lyrics as an outlet for her feelings, and her mother commented, "Her initial writings were always very introspective. Some of it was very black, and very deep, almost worrisome."

Pink began performing in Philadelphia clubs when she was about 14 years old. She adopted her nickname "Pink" as her stage name around this time. She has given different explanations about how she came to be given that nickname, which she has had since she was a child. At 14, she was convinced to audition to become a member of the all-female group Basic Instinct, and earned a spot in the lineup. Ultimately, the group disbanded without releasing any material.

At 15, Pink and two other teenage girls, Sharon Flanagan and Chrissy Conway, formed the R&B group Choice. A copy of their first song, "Key to My Heart", was sent to LaFace Records in Atlanta, Georgia, where L.A. Reid overheard it and arranged for the group to fly there so he could see them perform. Afterward, he signed them to a recording contract with the label. Since the three girls were under 18 at the time, their parents had to cosign the contract. The group relocated to the label's then-headquarters in Atlanta to record an album. Despite it failing to see a commercial release, their song "Key to My Heart" appeared on the soundtrack to the 1996 film Kazaam. During a Christmas party, Reid gave Pink an ultimatum: "go solo or go home." Choice subsequently disbanded in 1998.
