C.V. Pothuusburg is a carnival association that brings the Dutch town of Grave to life during carnival, when it becomes Pothuusburg. The celebration is led by a prince or princess, supported by an adjudant, the Vorst, the Council of Eleven and the Grote Garde. Festivities take place over several days in local pubs and the Pothuusburcht, with residents and visitors joining the carnival atmosphere.

The association also gives young people a central role. Each year, a youth prince or princess leads the youth of Pothuusburg, who take part in processions, ride on the parade float and celebrate together in the Pothuusburcht. A long-running highlight is the Pothuusburgse Pronkzittingen, staged for more than 55 years. These shows feature locally created comedy, performances, dance and singing, with two days of events each year.

C.V. Pothuusburg sells carnival merchandise through its online store and pop-up shop, and offers membership for people who want to support carnival in Grave. The association is run by a team of officers and event volunteers.
