2015–16 Belgian Second Division

The 2015–16 season of the Belgian Second Division (also known as Proximus League for sponsorship reasons) began on 8 August 2015 and ended in April 2016.

Structural changes
This season was the last under the name Second Division. Starting from 2016-17 the league is known as First Division B as a result of reforms in the Belgian league system. The champions were promoted and 9 teams relegated to the third division named Amateur First Division or Amateur Superleague, while no team was promoted from the lower division. Promotion playoffs were not played and three-period rankings were not applied.
