FK Željezničar is one of the most iconic and successful football clubs in Bosnia and Herzegovina, based in the capital city of Sarajevo and competing in the Premier League of Bosnia and Herzegovina. The club's full name is Fudbalski Klub Željezničar Sarajevo, and it plays its home games at the legendary Grbavica Stadium. Founded in 1921, the team is famously known as "The Blues" for their primary kit color. The club was originally formed by railway workers, which is reflected in its name meaning "railwayman."

In the modern Bosnian league, Željezničar remains a powerhouse, having won multiple domestic league and cup titles, and regularly competing in European competitions. The current squad blends youth academy products with experienced signings. The fan base, known as "The Blue Union," is renowned for its passionate and unwavering support, creating an intimidating atmosphere at Grbavica.
