AFC Ajax is a Dutch professional football club founded in Amsterdam in 1900 and named after the Greek hero of the Trojan War. Since 1996 it has played at the Johan Cruyff Arena, a covered stadium of nearly 56,000 seats named after the club's greatest player.

Ajax is by some distance the most successful club in the Netherlands, with a record number of Eredivisie titles and around twenty KNVB Cups. Under Rinus Michels and Cruyff it defined Total Football, winning three consecutive European Cups from 1971 to 1973, and a young side coached by Louis van Gaal added a fourth in 1995 alongside the UEFA Cup of 1992 and the Intercontinental Cup. Its academy remains one of the most respected in world football, and the club competes in the Eredivisie.
