The 2017–18 season was the 58th season in the history of Nogometni klub Maribor. It began on 1 June 2017 and concluded on 31 May 2018, with competitive matches played between July and May. It was the first season since 2007–08 in which Maribor did not win a single trophy during the season as the team lost the league title to Olimpija Ljubljana due to worse head-to-head record after finishing with the same number of points (80) in 36 rounds. Olimpija also eliminated Maribor in the quarter-finals of the Slovenian Cup. However, Maribor fared better in European competitions as the team reached the group stages of the UEFA Champions League for the third time in club's history.
