Original Robey training shirt Willem II 2015/16

The Eredivisie 2015-2016 of Willem II was the 61st season of the Dutch professional football club since the introduction of professional football in 1954. The club also played in the Eredivisie this season due to the 9th place in the previous season.

On 25 March, the club formally announced that it would cancel the contracts of eight players or not raise the option to extend. It concerned David Meul, Frank van der Struijk, Robert Braber, Robbie Haemhouts, Adam Nemec, Nick van der Velden, Nicky Kuiper and Justin Mathieu. It was later decided not to exercise the option in Lesly de Sa's contract either. The options in the contracts of Anouar Kali and Nigel Bertrams were used.
