Darwin Gabriel Núñez Ribeiro (born 24 June 1999) is a Uruguayan professional footballer who plays as a striker for Premier League club Liverpool and the Uruguay national team.

Núñez came through Peñarol's youth academy, being promoted to the first team in 2017. In August 2019, he joined Spanish Segunda División club Almería for a club record fee. Benfica signed him in 2020 for a club-record transfer worth €24 million, the most expensive signing in Portuguese football history. In his second season, he won the Bola de Prata for top scorer in the Primeira Liga with 26 goals in 28 games, being named in the Primeira Liga Team of the Year and Primeira Liga Player of the Year. Liverpool then signed him in 2022 for a transfer worth €75 million (£64 million). In his first competitive game for the club, he scored as they achieved victory in the 2022 FA Community Shield.

After representing Uruguay at various youth levels, Núñez was called up to the senior national team for his first time in 2019. He scored on his international debut against Peru. After missing the 2021 Copa América due to an injury, Núñez represented Uruguay at the 2022 FIFA World Cup.
