Leonardus Johannes Petrus Maria (Léon) Frissen (Beek, 24 June 1950) was Queen's Commissioner or Queen's Governor of the province of Limburg, Netherlands.
In the Dutch province of Limburg, the Queen's Commissioner is usually called "Gouverneur" (governor), as in Belgium. Similarly, the "Provinciehuis" (Province Hall) at Maastricht is called "Gouvernement" (Governor's Residence). This local custom arose from the particular status of the current province in the nineteenth century.
