The Central Criminal Court of England and Wales, commonly referred to as the Old Bailey after the street on which it stands, is a criminal court building in central London, one of several that house the Crown Court of England and Wales. The street outside follows the route of the ancient wall around the City of London, which was part of the fortification's bailey, hence the metonymic name.

A court is any person or institution, often as a government institution, with the authority to adjudicate legal disputes between parties and carry out the administration of justice in civil, criminal, and administrative matters in accordance with the rule of law. In both common law and civil law legal systems, courts are the central means for dispute resolution, and it is generally understood that all people have an ability to bring their claims before a court. Similarly, the rights of those accused of a crime include the right to present a defense before a court.
