Andrey Nascimento dos Santos (আন্দ্রে সান্তোস) is a Brazilian professional footballer who plays as a midfielder for Premier League club Chelsea and the Brazil national team.

At the age of four, Santos was introduced to futsal in an effort to lose weight. He fell in love with the game, and began playing as a defender, before being moved up to midfield during his time in Vasco da Gama's youth academy.

On 6 March 2021, at the age of 16, Santos made his professional debut for Vasco da Gama as an 85th-minute substitute in a 1–0 Campeonato Carioca loss away to Volta Redonda. He would go on to make his league debut in a 3–0 Série B defeat away to Londrina on 28 November 2021. In the 2022 season, Vasco manager Zé Ricardo made Santos a starter in the team, propelling his career to new heights. He became the youngest goalscorer in the club's history on 7 June 2022, netting in a 3–2 Série B victory away to Náutico.

On 6 January 2023, Vasco da Gama announced that Santos had departed the club to join Premier League club Chelsea.

On 2 March 2023, he returned to Vasco on loan until 30 June 2023.

On 25 August 2023, Chelsea announced Santos' season-long loan to Nottingham Forest. He made his debut for Forest five days later on 30 August 2023, in the EFL Cup in a 1–0 defeat to Burnley. He made his Premier League debut on 29 October 2023, against Liverpool at Anfield in a 3–0 defeat. He was recalled from Nottingham Forest on 4 January 2024 after Santos only made two appearances in 5 months.

On 1 February 2024, Santos was loaned to Ligue 1 club Strasbourg until the end of the season. He made his debut for Strasbourg on 8 February 2024, in a 3–1 defeat to Lorient in Ligue 1. His first goal for the club came on 12 May 2024, scoring the winning goal in extra time in a 2–1 win against Metz. The loan was extended for one more season on 2 August 2024.

Santos represented Brazil's under-15s at the 2019 South American U-15 Championship. He has also represented his nation at under-20 level. Santos captained the under-20s en route to an undefeated title in the 2023 South American U-20 Championship, scoring a joint-top six goals during the tournament. In March 2023, Santos was called-up by interim coach Ramon Menezes for Brazil's friendly away at Morocco, where he made his debut as a starter in a 2–1 loss.
