Alecia Beth Moore Hart (born September 8, 1979), known professionally as Pink (stylized as P!nk), is an American singer and songwriter. She is known for her rock-influenced pop songs, powerful contralto voice, 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 moderate 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 Billboard Hot 100-top ten singles: "There You Go" and "Most Girls". Pink gained further recognition for her 2001 collaborative single "Lady Marmalade" (with Christina Aguilera, Missy Elliot, Lil' Kim and Mýa), which was released for the Moulin Rouge! soundtrack and 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 number-one single "So What". Pink's sixth album, The Truth About Love (2012), became her first to debut and peak at #1 on the Billboard 200 and spawned her fourth US number-one single, "Just Give Me a Reason" (featuring Nate Ruess). In 2014, Pink formed the collaborative folk duo You+Me with Canadian musician Dallas Green, whom 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 likewise debuted and peaked at #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 been described as "pop royalty" for her distinctive raspy voice and acrobatic stage presence. She 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.
