The Johan Cruyff Arena (Dutch: Johan Cruijff Arena [ˈjoːɦɑŋ ˈkrœyf aːˌreːnaː]; officially stylised as Johan Cruijff ArenA) is the main stadium of the Dutch capital city of Amsterdam and the home stadium of football club AFC Ajax since its opening. Built from 1993 to 1996 at a cost equivalent to €140 million, it is the largest stadium in the country. The stadium was previously known as the Amsterdam Arena (stylised as Amsterdam ArenA) until the 2018–19 football season, when it was officially renamed in honor of legendary Dutch footballer Johan Cruyff (1947–2016) who died in March 2016.

It was one of the stadiums used during UEFA Euro 2000, and also held the 1998 UEFA Champions League Final and 2013 UEFA Europa League Final. The stadium also hosted three group stage matches and one match in the round of 16 of the UEFA Euro 2020.

Both international and Dutch artists have given concerts in the stadium, including Tina Turner, Coldplay, U2, Take That, Celine Dion, Madonna, Michael Jackson, André Hazes, David Bowie, AC/DC, Justin Timberlake, One Direction, The Rolling Stones, Beyoncé, Rihanna, and Armin van Buuren. The dance event Sensation was held in the stadium every year, up until the final edition in 2017.

The stadium has a retractable roof and a grass surface. Since 2022, the stadium has a capacity of 56,130 people during football matches, increased from 54,990. The stadium has a capacity of 68,000 during concerts if a center-stage setup is used (the stage in the middle of the pitch); for end-stage concerts, the capacity is 50,000; and for concerts for which the stage is located in the east side of the stadium, the capacity is 35,000. It held UEFA five-star stadium status, which was superseded by a new system of classification.
