The Crown of Ireland Act 1542 (33 Hen. 8. c. 1 (I)) is an Act that was passed by the Parliament of Ireland on 18 June 1542, which created the title of "King of Ireland" for monarchs of England and their successors; previous monarchs had ruled Ireland as Lords of Ireland. The first monarch to hold the title was King Henry VIII of England.

The long title of the Act was "An Act that the King of England, his Heirs and Successors, be Kings of Ireland". Among the 18th-century Irish Patriot Party it was called the Act of Annexation.
