The Friends of the Monarchist Constitution, commonly known as the Monarchist Club or the Monarchiens, were one of the revolutionary factions in the earliest stages of the French Revolution. The Monarchiens were briefly a centrist stabilising force criticized by the left-wing of the National Constituent Assembly, the spectators in the galleries and the patriotic press. Established in August 1789, the Monarchist Club was quickly swept away. Specifically, the brief movement developed when the Revolution was shifting away from the Ancien Régime during the Spring of 1789 and was defeated by the end of 1789. Subsequently, the term itself is usually derogatory.

The National Constituent Assembly was a constituent assembly in the Kingdom of France formed from the National Assembly on 9 July 1789 during the first stages of the French Revolution. It dissolved on 30 September 1791 and was succeeded by the Legislative Assembly.
