2017–18 Basketligan season

Luleå was the defending champion, but failed to repeat as they lost in the last game of the finals to Norrköping Dolphins, that achieved their fifth title ever.

The participating teams first played a conventional round-robin schedule with every team playing each opponent four times for a total of 28 games.

After the end of the 2016–17 season, Malbas decided to not continue playing at Basketligan.
