NK Varaždin (1931–2015)

Varaždinski športski nogometni klub Varaždin (English: Varaždin Football Club), commonly referred to as VŠNK Varaždin or simply Varaždin, was a Croatian football club based in the city of Varaždin in the north of the country. For the majority of its existence between 1958 and 2010, the club was known as NK Varteks, honouring the name of its principal sponsor, a local textile factory.

The club spent its entire history in the Yugoslav era in lower-tier divisions. However, after Croatia's independence in 1991 and the formation of the Croatian First Football League Varteks established themselves as one of the stronger sides in the new national top level. Varteks spent the next 21 seasons in Croatia's top league, finishing third three times, and reaching the national cup final on six occasions.

During this period, the club also regularly played European football, with their biggest successes in the 1998–99 season, when they reached the quarter-final of the UEFA Cup Winners' Cup, and in the 2001–02 season, when they knocked out England's Aston Villa in the first round of the UEFA Cup.

By the early 2010s both the club and the factory were in dire financial problems. In 2010 the club dropped the Varteks name, which led to angry fans forming their own club, the new NK Varteks, in 2011. In 2012 the club, now called Varaždin, were relegated from the league, and in 2013 they were suspended and sent to the third level. They languished there for two more seasons before finally folding in 2015.

The club played their home matches at the Stadion Varteks, which was renovated through the years and reached an all-seating capacity of 10,800 (further renovated to seat 8,800 by sometime before 2021).
