The secretary of state for protestant affairs (French: Secrétaire d'État de la Religion Prétendue Réformée, or R.P.R., the "So-called Reformed Religion"), was the secretary of state in France during the "Ancien Régime" and Bourbon Restoration in charge of overseeing French Protestant affairs. From 1749 on, the position was combined with the position of secretary of state of the Maison du Roi.
