The 2017–18 Basketball Bundesliga, known as the easyCredit BBL for sponsorship reasons, was the 52nd season of the Basketball Bundesliga (BBL), the top-tier level of professional club basketball in Germany. The defending champion was Brose Bamberg. The regular season started on 29 September 2017 and ended 1 May 2018.
For the first time in BBL history, two windows for FIBA national team play were planned in which the competition stopped. These were in November 2017 and February 2018.[2]
A number of nine teams participated in European club competitions this season, the highest number ever in German basketball history.[3]
In the regular season, teams played against each other two times home-and-away in a round-robin format. The first eight teams advanced to the playoffs. The last two placed teams were relegated to the ProA for next season. The regular season started on 29 September 2017 and concluded 1 May 2018.
^Rockets Gotha started the season as "Oettinger Rockets", named after its main sponsor Oettinger Brauerei. However, from January 2018 the main sponsor left and the club would be simply known as "Rockets".[7]
