The '''Treason Act 1766'''{{efn|name=st}} ([[6 Geo. 3]]. c. 53) was an [[Act of Parliament (United Kingdom)|act]] of the [[Parliament of Great Britain]]. The [[long title]] was "An Act for altering the Oath of Abjuration and the Assurance; and for amending so much of an Act of the Seventh Year of her late Majesty Queen Anne, intituled, [[Treason Act 1708|An Act for the Improvement of the Union of the two Kingdoms]], as, after the Time therein limited, requires the Delivery of certain Lists and Copies therein mentioned to Persons indicted of [[high treason|High Treason]], or [[misprision of treason|Misprision of Treason]]."

Sections 1 and 2 of the act were concerned with the [[oath of abjuration]]. Section 3 of the act disapplied certain procedural requirements in cases of high treason consisting of [[counterfeit]]ing the king's coin; namely the requirement in section 11 of the [[Treason Act 1708]] ([[7 Ann.]] c. 21) that the accused be given a list of the witnesses and the jurors. (This requirement had only come into force in 1766, on the death of [[James Francis Edward Stuart]], the [[Jacobitism|Jacobite]] pretender to the throne.)

== Subsequent developments == The whole act was repealed on 15 June 1945 by section 2(1) of, and the schedule to, the [[Treason Act 1945]] ([[8 & 9 Geo. 6]]. c. 44).
