Janet Damita Jo Jackson (born May 16, 1966) is an American singer, songwriter, actress, and dancer. She is noted for her innovative, socially conscious and sexually provocative records, as well as elaborate stage shows. Her sound and choreography became a catalyst in the growth of MTV, enabling her to rise to prominence while breaking gender and racial barriers in the process. Lyrical content that focused on social issues and lived experiences set her reputation as a role model for youth.

The tenth and youngest child of the Jackson family, Jackson starred in multiple television shows throughout the 1970s and early 1980s, before signing a recording contract with A&M Records and releasing her self-titled debut album in 1982. She became a pop icon following the releases of the albums Control (1986) and Rhythm Nation 1814 (1989). Her collaborations with record producers Jimmy Jam and Terry Lewis incorporated a variety of music genres, which led to crossover success in popular music. In 1991, Jackson signed the first of two record-breaking multimillion-dollar contracts with Virgin Records, becoming one of the highest-paid artists in the industry. She established her image as a sex symbol with a leading role in the film Poetic Justice (1993), and the albums Janet (1993) and The Velvet Rope (1997). Billboard named her the second most successful artist of the 1990s in the United States after Mariah Carey.

The release of her seventh studio album All for You in 2001 coincided with Jackson being the subject of the first MTV Icon special. By the end of the year, she joined her brother Michael as one of the few artists to score ten Billboard Hot 100 number-one singles. However, the backlash from the 2004 Super Bowl XXXVIII halftime show controversy resulted in an industry blacklisting under the direction of Les Moonves, then-CEO of CBS. Jackson subsequently experienced reduced radio airplay, televised promotion and sales figures from that point forward. After parting ways with Virgin Records, she released her tenth studio album Discipline (2008), her first and only album with Island Records. In 2015, she partnered with BMG Rights Management to launch her own record label, Rhythm Nation, and released her eleventh studio album, Unbreakable, the same year. Since then she has continued to release music as an independent artist.

Jackson has sold over 100 million records, making her one of the world's best-selling music artists. She holds the record for the most consecutive top-ten entries on the US Billboard Hot 100 by a female artist (18) and remains the only artist in the history of the chart to have seven singles from one album (Rhythm Nation 1814) peak within the top five positions. In 2008, Billboard placed her number seven on its list of the Hot 100 All-Time Top Artists, and in 2010 ranked her fifth among the "Top 50 R&B/Hip-Hop Artists of the Past 25 Years". In 2016, the magazine named her the second most successful dance club artist after Madonna. Her accolades include five Grammy Awards, eleven Billboard Music Awards, eleven American Music Awards, an Academy Award nomination, a star on the Hollywood Walk of Fame, and eight Guinness World Records entries. In 2019, she was inducted to the Rock and Roll Hall of Fame.
