The term "Red Priests" or "Philosopher Priests" is a modern historiographical term that refers to Catholic priests who, to varying degrees, supported the French Revolution (1789-1799). The term "Red Priests" was coined in 1901 by Gilbert Brégail and later adopted by Edmond Campagnac. However, it is anachronistic because the color red, associated with socialist movements since 1848, did not signify supporters of the French Revolution, who were referred to as "Blues" during the civil wars of 1793–1799, in contrast to the royalist "Whites." Hence, a recent historian suggested using the term "Philosopher Priests" to describe this group, a term used at the time to refer to these priests.

Jacques Roux was a radical Roman Catholic Red priest who took an active role in politics during the French Revolution. He skillfully expounded the ideals of popular democracy and classless society to crowds of Parisian sans-culottes, working class wage earners and shopkeepers, radicalizing them into a revolutionary force. He became a leader of a popular far-left.
