Jahseh Dwayne Ricardo Onfroy (January 23, 1998 – June 18, 2018), known professionally as XXXTentacion, was an American rapper, singer and songwriter. A controversial figure within the hip hop industry, Onfroy has been regarded to have left behind "a huge musical footprint" due to his impact on his young fanbase and his popularity during his short career. His most notable appearance is his tattoos and his distinctive half-colored hair, which was constantly changed throughout his career.

Born in Plantation, Florida, Onfroy spent most of his childhood in Lauderhill. He began writing music after being released from a juvenile detention center and started his music career on SoundCloud in 2013, where he soon became a popular figure in SoundCloud rap, a trap scene that takes elements of lo-fi music and harsh 808s. Onfroy rose to prominence with the song "Look at Me" which is now certified Platinum by the Recording Industry Association of America (RIAA). He released his debut album, 17, on August 25, 2017, which debuted at number 2 on the US Billboard 200, receiving a positive response from critics, some of which lauded the album for its personal narratives and diverse musical style. On August 15, 2018, the album was certified Platinum by the Recording Industry Association of America. Onfroy's second album, ?, was released on March 16, 2018, and it debuted at number one on the Billboard 200, with its singles "Sad!", "Changes" and "Moonlight" all reaching the top 20 of the Billboard Hot 100. The album was certified Platinum by the Recording Industry Association of America (RIAA) on August 7, 2018. In the week following his death, Onfroy's highest-charting single, "Sad!", went from 52nd to 1st on the Billboard Hot 100, making him the first artist to top the Hot 100 posthumously in a lead role since The Notorious B.I.G., with "Mo Money Mo Problems", in 1997.

On June 18, 2018, Onfroy was fatally shot at the age of 20, in a robbery at a motorcycle dealership in Deerfield Beach, Florida. The attackers fled the scene in an SUV after stealing a Louis Vuitton bag with $50,000 in it from Onfroy.
