What Is the Third Estate? (French: Qu'est-ce que le Tiers-État?) is a political pamphlet written in January 1789, shortly before the outbreak of the French Revolution, by the French writer and clergyman Abbé Emmanuel Joseph Sieyès (1748–1836). The pamphlet was Sieyès' response to finance minister Jacques Necker's invitation for writers to state how they thought the Estates-General should be organized.
