Christian Renoux is a French historian and an activist for nonviolence.

Born in 1960, he is alumnus of the École normale supérieure de Fontenay-Saint-Cloud (1982), agrégé in History (1984), alumnus of the École française de Rome, the French Historical Institute of Rome (1992–1995), doctor in Early modern History of the Paris 1 Panthéon-Sorbonne University (1996) and graduated in Catholic theology from the Marc Bloch University of Strasbourg.

He published an history of the Peace Prayer attributed to saint Francis of Assisi ("Lord, make me an instrument of your peace"), in which he demonstrated that this text, well known as the Prayer of Saint Francis and become in half a century one of the most famous worldwide prayers, appeared, anonymously, in 1912, in France, and has been wrongly attributed to saint Francis around 1925.

A conscientious objector, he served during his obligatory civilian service (1985–1987) at the Cahiers de la Réconciliation, magazine of the MIR, French branch of the International Fellowship of Reconciliation (IFOR).

Since November 2000, he has been the MIR France representative to the National Committee and president of the French Coalition for the Decade for the Culture of Peace and Nonviolence (2001–2010), which became in April 2011 the Coalition for the Education for Nonviolence and Peace.
