The Society of the Friends of the Rights of Man and of the Citizen (French: Société des Amis des droits de l'homme et du citoyen [sɔsjete dez‿ami de dʁwa də lɔm e dy sitwajɛ̃]), mainly known as Cordeliers Club (French: Club des Cordeliers [klœb de kɔʁdəlje]), was a populist political club during the French Revolution from 1790 to 1794, when the Reign of Terror ended and the Thermidorian Reaction began.

The club campaigned for universal male suffrage and direct democracy, including the referendum. It energetically served as a watchdog looking for signs of abuse of power by the men in power. By 1793, it was challenging the centralization of power by Robespierre and his Committee of Public Safety. They responded by arresting the leadership, charging them with conspiring to overthrow the Convention. The leaders were guillotined, and the club disappeared.

The club had its origins in the Cordeliers district, a famously radical area of Paris called, by Camille Desmoulins, "the only sanctuary where liberty has not been violated". Under the leadership of Georges Danton, this district had played a significant role in the Storming of the Bastille and was home to several notable figures of the Revolution, including Danton himself, Desmoulins and Jean-Paul Marat—on whose behalf the district placed itself in a state of civil rebellion, when in January 1790 it refused to allow the execution of a warrant for his arrest that had been issued by the Châtelet.

Having issued in November 1789 a declaration affirming its intent to "oppose, as much as we are able, all that the representatives of the Commune may undertake that is harmful to the general rights of our constituents", the Cordeliers district remained in conflict with the Parisian government throughout the winter and spring of 1790. In May and June 1790, the previous division of Paris into 60 districts was by decree of the National Assembly replaced by the creation of 48 sections. This restructuring abolished the Cordeliers district.

Anticipating this dissolution, the leaders of the Cordeliers district founded in April 1790 the Société des Amis des droits de l’homme et du citoyen, a popular society which would serve as an alternative means of pursuing the goals and interests of the district. This society held its meetings in the Cordeliers Convent and quickly became known as the Club des Cordeliers. It took as its motto the phrase Liberté, égalité, fraternité, and because its aim was to keep an eye on the government its emblem was an open eye.

The membership fees of this society were fixed low and thus affordable to a more diverse range of citizens than those of many other political clubs at the time, including the Jacobin Club. There were no other restrictions on membership. The Cordeliers presented themselves as exceptionally populist and they prided themselves on counting working men and women among their members. A contemporary account describes one meeting:

About three hundred persons of both sexes filled the place; their dress was so unkempt and so filthy that one would have taken them for a gathering of beggars. The Declaration of the Rights of Man was stuck on the wall, crowned by crossed daggers. Plaster busts of Brutus and William Tell were placed on each side, as if expressly to guard the Declaration. Facing, behind the tribune, as supporters, there appeared busts of Mirabeau and Helvétius, with Rousseau in the middle.

However, the preponderance of Cordeliers were members of the bourgeoisie and its leadership was largely drawn from the educated middle classes.
