is a Spanish professional footballer who plays as a goalkeeper for Serie A club Fiorentina. Considered one of the best keepers of his generation and one of the best ever Spanish goalkeepers, he is known for his reflexes, agility, and shot-stopping capabilities.

Born in Madrid, De Gea began his playing career with Atlético Madrid, rising through the academy system at the club before making his senior debut in 2009, aged 18. After being made Atlético's first-choice goalkeeper, he helped the team win the UEFA Europa League and the UEFA Super Cup in 2010. His performances subsequently attracted the attention of Manchester United, and De Gea joined the club in 2011 for £18.9 million, a British record for a goalkeeper at the time.

During his time in Manchester, De Gea made over 500 appearances and won a Premier League title, an FA Cup, two League Cups, three Community Shields and a second Europa League. For three consecutive seasons from 2013–14 to 2015–16, he was elected as United's Sir Matt Busby Player of the Year, the first player in the award's history to win on three successive occasions (four in total), as well as being included in four consecutive (five in total) PFA Team of the Year sides from 2015 to 2018. In 2018, he was named in the FIFA FIFPro World11. De Gea left United following the expiration of his contract in 2023, and, following a year away from football, joined Fiorentina.

Tipped by many as the successor to Iker Casillas as Spain's long-term goalkeeper, De Gea was the captain for the Spain under-21 national team that won the European Championship in 2011 and 2013, and also competed in the 2012 Summer Olympics. He made his debut for the senior team in 2014 and was selected for that year's World Cup. De Gea was named as Spain's starting goalkeeper for UEFA Euro 2016 and the 2018 FIFA World Cup, receiving criticism for his performance in the latter. He lost his regular place to Unai Simón for Euro 2020.
