Mýa Marie Harrison (born October 10, 1979), better known simply as Mýa /ˈmaɪ.ə/, is an American hip hop and R&B singer, songwriter and actress. Harrison's eponymous debut album with (through) Interscope Records was released in April 1998. It sold over one million copies in the United States, producing the gold-certified top ten single "It's All About Me" featuring Sisqó. Her second studio album, platinum-plus selling Fear of Flying was released in 2000 and became a worldwide success, with single "Case of the Ex" becoming Mýa's breakthrough hit, topping the Australian Singles Chart for two consecutive weeks.

In 2002, Harrison won a Grammy Award in the category for Best Pop Collaboration with Vocals for her rendition of Labelle's 1975 hit "Lady Marmalade", a cover version she recorded alongside Christina Aguilera, rapper Lil' Kim and Pink for the Moulin Rouge! soundtrack (2001). She released her third studio album, Moodring, in the summer of 2003. The album produced the smash hit "My Love Is Like...Wo" and was certified gold by the Recording Industry Association of America.

Following a label change to Universal Motown, Mýa's oft-delayed fourth studio album, Liberation (2007), received a download-release in Japan only after her label accidentally leaked the album. With the decision to go independent and a decline in her popularity in the United States, Harrison was offered a recording contract with Manhattan Recordings (a division of Lexington Corp.), a record label based in Japan. Through that label, she recorded two exclusive albums for the Japanese music market, Sugar & Spice (2008) and, most recently, K.I.S.S. (Keep It Sexy & Simple) (2011). In between recording those two albums, she launched her own independent record label Planet 9, and competed in Dancing with the Stars – season nine; finishing in second place.

Aside from a music career, Harrison branched out into acting; making her feature-film debut in 1999's thriller In Too Deep starring LL Cool J and Omar Epps. She continued to score supporting roles in films such as Chicago (winning a Screen Actors Guild Award for Best Ensemble Cast); Dirty Dancing: Havana Nights (2004); Shall We Dance? (2004); and Cursed (2005). She has endorsed several brands such as Coca-Cola, Gap, Iceberg, Tommy Hilfiger, and Motorola.

Harrison's contribution to music has earned her many accolades in the fields of pop and R&B music categories. In 2009, Billboard listed Mýa as one of their Hot 100 Artists of the 2000s; placing her in the 97th position. As of October 2009, she has sold 3.2 million albums in the United States alone and 7 million albums worldwide.
