Engelbert Des Bois (1578–1651) was the seventh bishop of Namur (1630–1651).
Des Bois was born in Brussels on 9 July 1578 to parents from Burgundy.
Urban VIII issued the papal bull In eminenti in 1641, condemning a number of propositions drawn from the writings of Cornelius Jansenius.
In 1643 Des Bois was the first bishop in the Habsburg Netherlands to publish the bull, which he did without government permission.
He died on 15 July 1651, at the Abbey of Saint-Gérard de Brogne.
