Kiari Kendrell Cephus (born December 14, 1991), known professionally as Offset, is an American rapper and songwriter. He rose to prominence as one third of the Atlanta-based hip hop trio Migos. Formed with fellow rappers Quavo and Takeoff in 2008, the group released four commercially successful studio albums—Yung Rich Nation (2015), Culture (2016), Culture II (2017) and Culture III (2021)—before disbanding in 2023.

As a solo act, he first released the collaborative album Without Warning (2017) with record producer Metro Boomin and fellow Georgia-based rapper 21 Savage. It peaked within the top ten of the Billboard 200 and spawned the single "Ric Flair Drip," which peaked at number 13 on the Billboard Hot 100. The following year, he guest appeared on Tyga's 2018 single "Taste", which became his first top ten hit on the latter chart as a soloist, and received diamond certification by the Recording Industry Association of America (RIAA). That same year, he appeared alongside Travis Scott on Kodak Black's single "Zeze", which peaked at number two on the chart.

Offset signed with Motown and Capitol Records as a solo act to release his debut studio album, Father of 4 (2019). A commercial success, the album matched Without Warning on the Billboard 200 and spawned the top 40 single "Clout" (featuring Cardi B), which was nominated for Best Rap Performance at the 62nd Annual Grammy Awards. Offset and Cardi B's 2023 follow-up single, "Jealousy", peaked at number 55 on the Billboard Hot 100 and served as lead single for his second studio album Set It Off (2023), which released in October of that year to similar success.

His marriage to fellow rapper Cardi B—with whom he has three children—has been heavily publicized; the couple separated in late 2023, filing for divorce in August 2024.
