Wasalu Muhammad Jaco (born February 16, 1982), better known by his stage name Lupe Fiasco ( LOO-pay), is an American rapper and record producer. He rose to fame in 2006 following the success of his debut album, Lupe Fiasco's Food & Liquor. He also performs as the frontman of rock band Japanese Cartoon under his real name. As an entrepreneur, Fiasco was the chief executive officer of 1st and 15th Entertainment.

Raised in Chicago, Fiasco developed an interest in hip hop after initially disliking the genre for its use of vulgarity and misogyny. After adopting the name Lupe Fiasco and recording songs in his father's basement, 19-year-old Fiasco joined a group called Da Pak. The group disbanded shortly after its inception, and Fiasco soon met rapper Jay-Z, who helped him sign a record deal with Atlantic Records.

In September 2006, Fiasco released his debut album Lupe Fiasco's Food & Liquor on the label, which received three Grammy nominations. He released his second album, Lupe Fiasco's The Cool, in December 2007. The lead single "Superstar" became his first top 40 hit on the Billboard Hot 100. After a two-year delay, his third album, Lasers, was released in May 2011 to mixed reviews; however, it became his first album to debut at number one on the Billboard 200. The album was preceded by his highest-charting single, "The Show Goes On", which peaked at number 9. He released his fourth album, Food & Liquor II: The Great American Rap Album Pt. 1, in September 2012. His fifth album, Tetsuo & Youth, released in January 2015. His sixth album, Drogas Light, released in February 2017. His seventh album, Drogas Wave, released in September 2018. His eighth album, Drill Music in Zion, was released in June 2022.

In addition to music, Fiasco has pursued other business ventures, including fashion. He runs two clothing lines, Righteous Kung-Fu and Trilly & Truly; he has designed sneakers for Reebok. He has been involved with charitable activities, including the Summit on the Summit expedition, and in 2010, he recorded a benefit single for victims of the 2010 Haiti earthquake. Fiasco is also noted for his anti-establishment views, which he has expressed in both interviews and his music.
