The Affair of the Placards () was an incident in which anti-Catholic posters appeared in public places in Paris and in four major provincial cities, Blois, Rouen, Tours and Orléans, in the night of the 17 to 18 October 1534.

In Paris, the King himself stood under the canopy where the Most Holy Eucharist was usually carried, making a clear political statement. In addition, a reward of a hundred écus was advertised for information leading to the arrest of the perpetrator or perpetrators, who were to be burned at the stake. Protestant sympathizers were soon identified and sent to the Châtelet. The first condemnations were pronounced 10 November; the
