The Supreme Court of the Netherlands, officially the High Council of the Netherlands, is the final court of appeal in civil, criminal and tax cases in the Netherlands, including Curaçao, Sint Maarten and Aruba. The Court was established on 1 October 1838 and is located in The Hague.

The criminal justice system of the Netherlands is the system of practices and institutions of the Netherlands directed at upholding social control, deterring and mitigating crime, and sanctioning those who violate laws with criminal penalties and rehabilitation efforts. The Netherlands' criminal code is based on the Napoleonic Code, imposed during the time of the French Empire. The Dutch largely kept the Napoleonic Code after their independence, but tempered it with a significantly more rehabilitative penological focus.
