NK Jarun is a football club based in the Jarun neighborhood of Zagreb, competing in the Croatian First Football League, the top division of Croatian football. The club takes its name from the popular Jarun lake and recreation area, embedding it within the city's sporting culture. Their home matches are played at a stadium that, while modest, provides an intense atmosphere. Founded as a community club, Jarun has risen through the ranks to reach the pinnacle of Croatian football, a testament to excellent youth development and shrewd management. While historically not among the traditional "big three" of Croatian football, their presence in the First League marks a significant achievement. The current era is defined by the challenge of establishing themselves as a permanent top-flight entity, avoiding relegation and aiming for mid-table security. The squad combines experienced professionals with graduates from their own academy, playing an organized and disciplined style. The fan base, though smaller than the giants, is fiercely loyal and creates a vibrant, vocal support on match days at their Jarun home.
