Daniel Hernandez (born May 8, 1996), known professionally as 6ix9ine (pronounced "six nine") or Tekashi 6ix9ine, is an American rapper. He is known for his unconventional appearance, controversial behavior and brute-force screaming technique in some of his songs.

Hernandez rose to fame in late 2017 with the release of his debut single "Gummo". The song peaked at number 12 on the US Billboard Hot 100 and was certified platinum by the RIAA. In early 2018, Hernandez released his debut mixtape, Day69, which debuted at number four on the Billboard 200 album chart. He earned his first top-ten entry on the Hot 100 with "Fefe", featuring Nicki Minaj and Murda Beatz, which peaked at number three.

His legal issues have been a subject of controversy. In 2015, Hernandez pled guilty to using a 13-year-old child in a sexual performance when he was eighteen years old
