Kasper Peter Schmeichel (born 5 November 1986) is a Danish professional footballer who plays as a goalkeeper for Scottish Premiership club Celtic and the Denmark national team.

Schmeichel began his career with Manchester City, but had loan spells with Darlington, Bury and Falkirk before he made his first-team debut. Although Schmeichel appeared to have made the City number 1 shirt his own at the start of the 2007–08 season, the emergence of Joe Hart resulted in Schmeichel being loaned to Cardiff City. The signing of Republic of Ireland international Shay Given in 2009 meant that Schmeichel fell even further down the pecking order at City, and he was allowed to link up with former manager Sven-Göran Eriksson at Notts County. He spent only one season with the Magpies as, while it was a very successful one for the club and the player himself, changes to the club's financial position made his departure necessary and his contract was terminated by mutual consent.

Schmeichel joined Leeds United in 2010, but again, his tenure at the club only lasted one season before he was transferred to Leicester City, where he again worked under Eriksson. Schmeichel went on to make 479 competitive appearances for Leicester over 11 years, during the most successful era in the club's history, winning the Championship in 2014, the Premier League in 2016, and both the FA Cup and FA Community Shield in 2021.

After spells with Nice and Anderlecht, Schmeichel returned to Scotland to sign with Celtic in July 2024. In his first season, he won a domestic double, lifting the Scottish League Cup in December 2024 and the Scottish Premiership in April 2025.

Schmeichel played seventeen games for Denmark under-21s. He was called up to the Denmark national team for the first time in 2011, and was part of their squad at UEFA Euro 2012, but did not make his senior debut until 2013. He has since made over 110 international appearances, and represented his country at the 2018 FIFA World Cup, Euro 2020, the 2022 World Cup and Euro 2024.

Kasper Schmeichel was born on 5 November 1986 in Copenhagen, Denmark. He is the son of Bente and former Denmark international goalkeeper Peter Schmeichel, and is of Polish descent through his paternal grandfather.

Schmeichel grew up in Denmark during his early years but spent most of his childhood living in England due to his father's playing career. He is a native speaker of both Danish and English and speaks with a Mancunian accent. He attended Hulme Hall Grammar School in Cheadle Hulme, Stockport, Greater Manchester, and he also attended Saint Julian's School in Portugal while his father played for Sporting CP in Lisbon. When Alex Bruce, son of Kasper Schmeichel's father's former Manchester United teammate Steve Bruce, joined Schmeichel at Leeds United, the move saw the two players re-unite after both had previously played football together on the streets as children after school.

Schmeichel started playing organised football in Portugal in 2000, while his father was part of Sporting CP. He played one season in the Estoril youth academy, in which he managed to win a championship. Commenting on his early footballing years, Schmeichel remarked: "Before [Estoril], it wasn't that serious. I have to admit that when I was very small, football did not interest me that much. It was mostly in short periods that it was fun, and then I had enough. So it only started to take shape when I was 12–13 years old".
