Nogometni klub Maribor, commonly referred to as NK Maribor or simply Maribor, is a professional football club based in Maribor, Slovenia, that competes in the Slovenian PrvaLiga, the top tier of Slovenian football. Nicknamed "the Purples", the club was founded on 12 December 1960. They are regarded as a symbol of Slovenian football, particularly in their home region of Styria in northeastern Slovenia. Maribor have won a record 14 Slovenian PrvaLiga titles, 9 Slovenian Cups and 4 Slovenian Supercups. The club's most successful period was in the late 1990s and early 2000s, when they won seven successive league titles. Following the 2008–09 season, Maribor became the major force in Slovenian football for the second time, having won seven out of ten championships since then. Prior to Slovenia's independence in 1991, Maribor played in the Yugoslav football system, where the club, apart from winning the Yugoslav second division in 1967, had no major successes. Maribor are one of only three Slovenian teams which participated in the country's highest division, Yugoslav First League, between the end of World War II in 1945 and the breakup of Yugoslavia in 1991.
