John Cook or Cooke (baptised 18 September 1608 – 16 October 1660) was the first Solicitor General of the English Commonwealth and led the prosecution of Charles I. Following The Restoration, Cook was convicted of regicide and hanged, drawn and quartered on 16 October 1660. He is considered an international legal icon and progenitor of international criminal law for being the first lawyer to prosecute a head of state for crimes against his people.
