Royal charters applying to Cornwall

This is a list of charters promulgated by kings of England that specifically relate to Cornwall, which was incorporated into the Kingdom of England late in the Anglo-Saxon period. In the 9th and 10th centuries, the kings of Wessex became the rulers of Cornwall, and after a period of independence during the wars with the Danes, this rule by the kings of England became permanent (see History of Cornwall). The charters below relate either to the tin mines of Cornwall and Devon or to the Earldom or Duchy of Cornwall. The stannary charters are dated between 1201 and 1508, the others between 1231 and 1338.

In 1337, the earldom of Cornwall was made into a royal duchy to support the heir to the throne. Centralisation in the reign of Henry VIII meant that Cornwall's distinct status was no longer recognised in royal documents; though unlike the situation for Wales, no legislation was enacted to formalise this. The rights of the Duke of Cornwall still rely on medieval legislation. When no one is duke of Cornwall, the lands and rights of the Duchy are exercised by the Crown since the heir apparent may not always inherit the Duchy.
