The King's commissioner is the head of a province in the Netherlands. The officeholder chairs both the States Provincial and the Provincial Executive, but has a right to vote only in the latter. When the reigning monarch is a female, the office is known as Queen's commissioner. As there are twelve provinces in the Netherlands, there are twelve King's commissioners.

There are twelve provinces of the Netherlands representing the administrative layer between the national government and the local governments, with responsibility for matters of subnational or regional importance.
