George Haydock was a 16th-century English Catholic priest who was executed at Tyburn in 1584. Born in Lancashire to the family of Evan Haydock, he studied at the English College in Rome and was ordained in 1581. Following his return to England, he was apprehended in London after being identified by a former acquaintance. He spent over a year imprisoned in the Tower of London, where he maintained his devotion to the papacy and provided spiritual care to fellow prisoners.
