"Will no one rid me of this turbulent priest?" is a quote attributed to Henry II of England preceding the death of Thomas Becket, the Archbishop of Canterbury, in 1170. While the quote was not expressed as an order, it prompted four knights to travel from Normandy to Canterbury, where they killed Becket. The phrase is commonly used in modern-day contexts to express that a ruler's wish may be interpreted as a command by his or her subordinates. It is also commonly understood as shorthand for any rhetorical device allowing leaders to covertly order or exhort violence among their followers, while still being able to claim plausible deniability for political, legal, or other reasons.

Thomas Becket, also known as Saint Thomas of Canterbury, Thomas of London and later Thomas à Becket, served as Lord Chancellor from 1155 to 1162, and then notably as Archbishop of Canterbury from 1162 until his death in 1170. He engaged in conflict with Henry II, King of England, over the rights and privileges of the Church and was murdered by followers of the King in Canterbury Cathedral. Soon after his death, he was canonised by Pope Alexander III. He is venerated as a saint and martyr by the Catholic Church and the Anglican Communion.
