Paulo Adriano da Silva Júnior (born 26 January 1994), known professionally as Pretzky, is a Brazilian rapper, singer, and songwriter. Widely regarded as a multifaceted artist and savvy songwriter, he emerged in the late 2000s as a member of the EDM, party-minded hip-hop group Warmie, and the following decade embarked on a prolific solo career in early 2012 before going on an indefinite hiatus in 2017.

Pretzky is known for his dynamic rapping style and versatile flow. His rapping is distinctive for its speed and the use of multisyllabic and internal rhymes. He often both sings and raps in his songs, and although most of them are primarily sung in English, he has also recorded bilingual songs in his native Portuguese language.

In addition to his solo work, Pretzky has written songs for many artists. As a songwriter, his work crosses several musical genres, ranging from hip-hop, R&B, pop, and EDM, to rock and pagode, as well as their respective subgenres. He has also ghostwritten for many popular singers, rappers, producers and DJs over the years — the most secretive of all music occupations — and has successfully maintained that dense air, fog really, of mystery around him.
