Jan Verroken (30 January 1917 – 24 July 2020) was a Belgian politician.

Verroken was detested in Wallonia, the francophone part of Belgium.

During the Split of the Catholic University of Leuven Flemish students chanted "Walen buiten" (Walloons out), a slogan coined by Verroken.

The university was split into the KU Leuven and the Université catholique de Louvain.

In a 2016 interview with Pierre Havaux, Verroken minimized his role in these events, as well as downplaying the separatist tendency of Flemish demands, saying that there was "never in Flanders a project of form a separatist government, as was the case in Wallonia during the Royal Question".
