N.I.N.A (also known as Nina do Porte) is a Brazilian rapper, DJ, and songwriter from Rio de Janeiro who came up through the grime/drill underground after starting out as a baile-funk DJ and crate-digging selector around 2017. Early scene work and collaborations laid the groundwork for her debut full-length A Bruta, a Braba, a Forte in 2020, a title that doubled as a statement of intent. She followed with singles and guest spots that sharpened a tougher, bass-driven sound while addressing street perspectives and gender representation in Brazilian rap. In 2023 she issued Para Todos os Garotos que já Mamei and released the single “Quem que tá vindo no porte?” with D38 and Terra, linking Rio and Brasília circles and expanding her audience beyond local showcases. Across this period she kept up a visible presence as a DJ and performer, often emphasizing that her path ran from the booth to the mic. Her profile widened in 2025 with the EP O Jogo Virou, supported by listening sessions and independent promotion, closing a multi-year run that traced her evolution from neighborhood parties to nationally noticed grime/drill releases.
