Christian Dannemann Eriksen (Danish pronunciation: [ˈkʰʁɛs.tjæn ˈeː.ʁɛg.sən]; born 14 February 1992) is a Danish professional footballer who plays as a midfielder for Bundesliga club VfL Wolfsburg and the Denmark national team.

Eriksen began his senior club career at age 18 in 2010, playing for Ajax, where he won three Eredivisie titles and the KNVB Cup. In 2013, Eriksen signed for Tottenham Hotspur in a transfer worth £11 million (€12.45 million), where he was twice named the club's Player of the Year, was voted into the 2017–18 PFA Team of the Year, and later also reached the 2019 UEFA Champions League final. In 2020, Eriksen joined Inter Milan in a transfer worth €19.7 million (£16.9 million), and won a Serie A title.

During a UEFA Euro 2020 match on 12 June 2021, Eriksen collapsed on the pitch after suffering a cardiac arrest; he was given cardiopulmonary resuscitation and was later fitted with an implantable cardioverter-defibrillator. He returned to football eight months later with a move to Premier League club Brentford, before transferring to Manchester United the following season. At United, he won an FA Cup and EFL Cup before departing the club after the 2024–25 season.

Eriksen made his senior international debut for Denmark in 2010 at age 18, and is currently the nation's record appearance holder with more than 140 caps, including appearing in six major tournaments; he was also the youngest player at the 2010 FIFA World Cup.

Born in Middelfart, Denmark, Eriksen followed in the footsteps of his father Thomas when he started playing football in the academy of local side, Middelfart G&BK. Eriksen's father was also one of the coaches at the time and in 2004 they helped the youth side finish unbeaten in the local youth championship for the third time in a period of four years.

The following year, he joined OB, who competed in the Danish youth championships, and within a year had helped the club to an age-group title. It was at OB that Eriksen first began showing signs of his technical ability, with his dribbling and free-kick techniques lauded by then-coach, Tonny Hermansen. His form at youth level attracted the attention of a number of major European clubs, including the likes of Chelsea and Barcelona. Eriksen ultimately underwent trials with both clubs as well as Real Madrid, Manchester United and Milan, but finally decided to move to Ajax, stating, "My first step should not be too big. I knew that playing in the Netherlands would be very good for my development. Then Ajax arrived and that was a fantastic option."

On 17 October 2008, Eriksen signed a two-and-a-half-year contract with Amsterdam-based club, Ajax. The transfer fee received by OB was estimated at €1 million (£847,199) while Middelfart also received a sum of €35 000 which they later used to construct a football pitch. He worked his way through the youth teams at Ajax and was promoted to the first team squad in January 2010, where he was given the number 51 shirt. Later that month, he made his first team debut in a 1–1 Eredivisie with NAC Breda. He scored his first goal for Ajax on 25 March in a 6–0 win over Go Ahead Eagles in the Dutch Cup and extended his contract with the club the following month. On 6 May, he played in the second match of the final of the 2009–10 Dutch Cup as Ajax beat Feyenoord 4–1, prevailing 6–1 on aggregate. At the end of his first professional season with the club, Eriksen had played 21 competitive matches, scoring one goal, and had made his international debut for Denmark. Eriksen's form throughout the campaign earned praise from manager Martin Jol who compared him to former youth products Wesley Sneijder and Rafael van der Vaart as well as Danish legend, Michael Laudrup for his reading of the game in the traditional number 10 role.

Eriksen took the number eight jersey ahead of the following campaign and began the 2010–11 season well, scoring his first Ajax league goal on 29 August 2010 in an away victory over De Graafschap. Over the course of the next few months, he scored his first home goal at the Amsterdam Arena, in a 3–0 Cup victory over BV Veendam, and his first European goal, in a 3–0 UEFA Europa League win over Anderlecht. In between the milestone goals, Eriksen was also named Danish Talent of the Year. His growing capabilities as the team's playmaker saw him become an undisputed starter in the side and he helped Ajax to their first Eredivisie title in seven years. At the end of the season he was named Ajax's Talent of the Year. His form throughout the campaign also earned him the Dutch Football Talent of the Year award which saw him become only the second Danish player to win the award since Jon Dahl Tomasson in 1996. Johan Cruyff, whose panel selected Eriksen for the award, described Eriksen as a typical product of the Danish school and added to previous comparisons between him and Brian and Michael Laudrup.
