Coifi or Cofi was the priest of the temple at Goodmanham in Northumbria in 627.
The dramatic overthrow of this temple in 627 AD by the high priest Coifi upon the conversion of King Edwin of Northumbria is related by St Bede in his History of the English Church and People (Historia ecclesiastica gentis Anglorum).
Coifi mounted a stallion and rode from the king's council (which according to local tradition was held at the royal summer encampment at Londsborough), to the Great temple of Woden at Goodmanham where he cast a spear into the altar before burning the temple to the ground, as the people watched and thought him mad.
