Jean-Joseph Ader (16 October 1796 – 12 April 1859) was a 19th-century French playwright, writer and historian.
He began his literary career by collaborating with the Diable boiteux, the Frondeur, the Pandore and the Mercure du XIXe siècle.
In 1826, he was sentenced to five days in jail against three months required for the anonymous article Robin des bois in the Frondeur which was assigned to him.
He then moved to Belgium where he founded the Constitutionnel des Pays-Bas with Pierre François Tissot, another quickly banned newspaper.
In July 1830, he was among the three hundred journalists and writers who wrote calls to insurrection to achieve the abdication of Charles X's monarchy.
