François-Marie Bigex (24 September 1751 – 19 February 1827) was a prominent Savoyard churchman who was appointed Bishop of Pinerolo in 1817 and then, in 1824, Archbishop of Chambéry. His life and career were much affected by the French wars which impacted Savoy directly between 1792 and 1815. He spent the most dangerous years of that period exiled in Lausanne, from where he was able to direct and undertake various missionary projects designed to combat the false doctrines that had arrived with the revolutionary armies from the west. His principle weapon in these endeavours was the pen.
