Pierre Cauchon (1371 – 18 December 1442) was a French Catholic prelate who served as Bishop of Beauvais from 1420 to 1432. He was a strong partisan of English interests in France during the latter years of the Hundred Years' War. He was the judge in the trial of Joan of Arc and played a key role in her execution. The Catholic Church overturned his verdict in 1456.
