Thomas Tunstall was a 17th-century English Catholic priest who was executed in Norwich. Born in Lancashire, he was associated with the family of Thurland Castle, though some historical records suggest he may have been born within the ancient Diocese of Carlisle. After completing his studies and receiving orders at Douay and Arras, he returned to England to serve as a priest. His ministry was cut short by his arrest, leading to a period of imprisonment and a failed attempt to escape from Wisbech Castle.
