Nogometni klub Maribor (English: Maribor Football Club) is a Slovenian professional football club based in Maribor, Slovenia. It competes in the Slovenian PrvaLiga, the top tier of the Slovenian football league system. Nicknamed "The Purples" (Vijolicasti), 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 15 Slovenian PrvaLiga titles, 9 Slovenian Cups and 4 Slovenian Supercups. The club won seven consecutive league titles between 1997 and 2003, and five consecutive titles between 2011 and 2015. Prior to Slovenia's independence in 1991, Maribor played in the Yugoslav football system. They won the Yugoslav second division in 1967 and were therefore promoted to the top-level Yugoslav First League, where they stayed until 1972. They are one of three Slovenian teams that participated in the Yugoslavia's highest division between the end of World War II in 1945 and the breakup of Yugoslavia in 1991.
Maribor is the only Slovenian club that reached the group stages of the UEFA Champions League and the UEFA Europa League. In addition, the club is one of the two founding members of the Slovenian PrvaLiga (along with Celje) which have never been relegated from the league since the inaugural 1991–92 season.
