A King's commissioner (Dutch: Commissaris van de Koning, CvdK) is the head of government and legislature in a province of the Netherlands.
When the reigning monarch is a woman, the title is Queen's commissioner (Commissaris van de Koningin).
A commissioner is appointed by the Dutch Crown as its official representative, and serves as the non-voting chair of the provincial legislature, the States-Provincial.
They are responsible for issues such as spatial planning and health care, within the bounds prescribed by the national government.
The King's Commissioner is appointed by the Dutch Crown, meaning the Council of Ministers of the Kingdom of the Netherlands, for a term of six years, renewable.
