Melissa Viviane Jefferson (born April 27, 1988), known professionally as Lizzo (), is an American rapper and singer. Born in Detroit, Michigan, she moved to Houston, Texas, with her family at the age of ten. After college, she moved to Minneapolis, Minnesota, where she began her recording career in hip hop music. Prior to signing with Nice Life Recording Company and Atlantic Records, Lizzo released two studio albums, Lizzobangers (2013) and Big Grrrl Small World (2015). Her first major-label extended play (EP), Coconut Oil, was released in 2016.

Lizzo attained mainstream success with the release of her third studio album, Cuz I Love You (2019), which peaked at number four on the US Billboard 200. The album spawned the singles "Juice" and "Tempo". The deluxe version of the album included Lizzo's 2017 single "Truth Hurts", which became a viral sleeper hit two years after its initial release. It topped the US Billboard Hot 100 and became the longest-leading solo song by a female rapper. Around this time, her 2016 single "Good as Hell" also climbed the charts, reaching the top ten of the Billboard Hot 100 and UK Singles Chart. Lizzo received eight nominations at the 62nd Annual Grammy Awards—the most for any artist that year—including nominations for each of the "Big Four" categories, and won the awards for Best Urban Contemporary Album, Best Pop Solo Performance for "Truth Hurts", and Best Traditional R&B Performance for the song "Jerome".

In 2021, Lizzo released the single "Rumors" (featuring Cardi B), which debuted in the top five of the Billboard Hot 100. Her fourth studio album, Special (2022), was preceded by its lead single "About Damn Time", which reached number one on the Billboard Hot 100 and made Lizzo the first black female singer since Whitney Houston in 1994 to win the Grammy Award for Record of the Year.

Along with her recording career, Lizzo has also worked as an actress; she performed a voice role in the animated film UglyDolls (2019), and appeared in the crime comedy-drama film Hustlers (2019). She is also the host of the Amazon Prime Video reality television series Lizzo's Watch Out for the Big Grrrls, for which she won the Primetime Emmy Award for Outstanding Competition Program. In 2019, Time named Lizzo "Entertainer of the Year" for her meteoric rise and contributions to music. In addition to four Grammy Awards, she has also won a Billboard Music Award, a BET Award, and two Soul Train Music Awards.
