Henri Arnaud (July 15, 1643 (and not 1641), Embrun, Hautes-Alpes – September 8, 1721) was a pastor of the Waldensians in Piedmont, who turned soldier in order to rescue, and who did rescue, his co-religionists from their dispersion under the persecution of Victor Amadeus II the Duke of Savoy.
When the Waldensians were exiled a second time, Arnaud accompanied them in their exile to Schönenberg, and continued to act as their pastor until his death.
