Jean-Jacques Renouard, seigneur de Villayer (24 June 1607, Nantes – 5 March 1691, Paris) was a member of the French Conseil d'État, which had been delegated special legal authorities by the absolutist reigning King Louis XIV.
In 1653 as the tenant of the Paris City Post, Renouard de Villayer ordered post boxes to be set up at different places in Paris.
Letters, prepaid with a uniform postage of 1 sol, could be put in these boxes and were then delivered inside of the city within the same day.
