Nogometni klub Maribor "B" (English: Maribor B Football Club), commonly referred to as NK Maribor B or simply Maribor B, was an association football club based in the city of Maribor, Slovenia. Founded in 2014, NK Maribor B was the reserve team of NK Maribor. The team was dissolved following the 2016–17 season. Reserve teams in Slovenia play in the same league system as the senior teams, however, they cannot play in the same competition as their senior teams, and thus, Maribor B was ineligible to play in the Slovenian PrvaLiga or the Slovenian Cup.
