Jeferson Forneck (born 14 December 2006), sometimes known as Jefinho, is a Brazilian professional footballer who plays as an attacking midfielder for Campeonato Brasileiro Série A club Grêmio.
Born in São Pedro da Serra, Rio Grande do Sul, Jeferson joined Grêmio's youth sides in 2017, aged ten. On 17 December 2022, he signed his first professional contract with the club, agreeing to a three-year deal.
Jeferson struggled with injuries in the following years, but still renewed his link until 2027 on 14 December 2025, after fully recovering. He was promoted to the first team ahead of the 2026 season, and made his professional debut on 21 January of that year, coming on as a second-half substitute for Dodi in a 2–0 Campeonato Gaúcho away win over Guarany de Bagé.
In November 2022, Jeferson debuted for the Brazil national under-17 team by scoring in a friendly match against Chile.
