Daley Blind (Dutch pronunciation: [ˈdeːli ˈblɪnt]; born 9 March 1990) is a Dutch professional footballer who plays for La Liga club Girona. He has been deployed in a variety of defensive roles – as a left-back, centre-back, and defensive midfielder. He is the son of former Ajax defender and former Netherlands national team manager Danny Blind.

Blind rose through the youth ranks at Ajax, becoming a regular after a loan to Groningen, and won four consecutive Eredivisie titles with the club. In September 2014, he transferred to Manchester United for £13.8 million, where he was part of the team that won four trophies including the FA Cup, EFL Cup and UEFA Europa League. In the summer of 2018, Blind returned to Ajax, where he won his fifth Eredivisie title and a first-ever KNVB Cup in his first season back at the club. He won two more Eredivisie titles before moving to Bayern Munich, where he won the Bundesliga during a six-month spell. Blind signed for Spanish club Girona in 2023.

A full Netherlands international from 2013 to 2024, Blind earned over 100 caps, and was a member of the Dutch squad that finished third at the 2014 FIFA World Cup. He went on to feature at UEFA Euro 2020, the 2022 World Cup and Euro 2024.

Blind began his career in the youth academy of his hometown club, Ajax; the same club where his father Danny made his name as a professional. Blind is a product of the Ajax youth system and, while officially still a B-junior, he became a mainstay in the A-juniors during the 2007–08 season before earning promotion to the Ajax first-team for the 2008–09 season. He showed good promise as a youngster and was made captain of Jong Ajax in 2007. He signed his first professional contract at the age of 17, tying him to the club until 1 July 2010.

On 7 December 2008, Blind made his debut in the Ajax first-team in the away match against FC Volendam. Blind made an immediate impact when he forced a corner kick through a Volendam defender, from which Jan Vertonghen scored the winning goal for Ajax. On 19 December 2008, he signed a contract extension keeping him with Ajax until 30 June 2013.

On 5 January 2010, he joined Groningen on loan for the remainder of the 2009–10 season, during the winter transfer window. At Groningen, Blind was mainly used as a right back. He was almost sold to Groningen for €1.5 million by Ajax on a permanent basis but the move did not materialize.

The following two seasons saw Blind contribute to two Eredivisie national championships with Ajax, for the 2010–11 season, and the 2011–12 season, the first of which would be Ajax's 30th championship title. However, Blind's performances when given the chance were unconvincing and he was even booed off the field in an Eredivisie game. Under newly appointed manager Frank de Boer, Blind would be given more and more trust and playing time, earning him the place as the first-choice left back with a permanent starting position during the 2012–13 season.

On 23 April 2013, it was announced by Marc Overmars that Ajax and Blind had reached an agreement to extend his contract for three years, binding him to the club until the summer of 2016. On 5 May, Blind contributed to Ajax's third Dutch Eredivisie title in a row, marking the club's 32nd national title, helping to defeat Willem II 5–0 at home, and securing the top position on the table just one match day from season's end. Later that day it was announced that Blind had been declared AFC Ajax Player of the Year for the 2012–13 season, after playing an outstanding fifth year for Ajax, from the starting left-back position.^{[citation needed]}
