Dinamo Zagreb is the most successful club in Croatian football, based at the Maksimir stadium in Zagreb. The club was founded on 9 June 1945 as the successor to the pre-war HŠK Građanski, established in 1911 and dissolved after the war for political reasons; Dinamo itself operated under the names HAŠK Građanski and Croatia Zagreb between 1991 and 2000, before reverting to its current name.
In the Croatian top division, Dinamo have won 26 league titles to date, including a run of 11 consecutive championships between 2005–06 and 2015–16. The club has also won the Croatian Cup on multiple occasions. Dinamo's main rival remains Hajduk Split, and matches between the two sides are known as the Eternal Derby.
On the European stage, Dinamo remain the only Croatian club to have won a continental trophy, lifting the Inter-Cities Fairs Cup, the forerunner of the UEFA Cup, in 1967, defeating England's Leeds United in the final (2-0 at home, 0-0 away). In subsequent decades, the team has regularly featured in the group stages of the Champions League and Europa League, recording notable wins over sides such as Arsenal (2015) and Chelsea (2022).
An important part of the club's operations is its youth academy, which has produced players including Luka Modrić, winner of the 2018 Ballon d'Or, as well as Mateo Kovačić and Joško Gvardiol. Dani Olmo also passed through Dinamo's academy, having joined it as a teenager. Academy graduates have for years formed a significant part of Croatia's national team, including the squad that reached the 2018 World Cup final.
