The 2016–17 DEL2 season was the fourth season since the founding of the DEL2, the second tier of German ice hockey, set below the Deutsche Eishockey Liga.

 Fourteen teams competed in the 2016–17 DEL2 regular season. EHC Bayreuth was promoted from Germany's third division, Oberliga. Each team played each other twice in the regular season, home and away, for a total of 52 matches each.

Teams placed seven to ten advanced to the championship playoff qualifiers, which followed a best of three format. The bottom four teams enter the relegation playoffs. The two losing teams from round 1 face off in the relegation final with the losing team being relegated to Oberliga.
 The DEL2 champion does not automatically get promoted to DEL. In September 2015, the DEL and DEL2 agreed to reintroduce promotion and relegation between the two leagues from the 2017–18 season onwards. The DEL2 champion would then have the opportunity to be promoted, provided it fulfilled the licensing requirements of the DEL, while the last-placed DEL club would be relegated.
