Charles Garnier, SJ (French pronunciation: [ʃaʁl ɡaʁnje]; baptised in Paris, May 25, 1606 – martyred December 7, 1649) was a Jesuit missionary working in New France.

Initially fobidden by his father from travelling to Canada, where he would face almost certain death as a missionary, he was eventually allowed to go.

[4] Embarking on March 25, 1636, he described the crossing in a letter to his father, We gave Viaticum to a sailor who had fallen from the top of the mizzenmast to the deck.

He was greatly influenced by a fellow missionary, Jean de Brébeuf, and was known as the "lamb" to Brebeuf's "lion".

When he learned that Brébeuf and Lalemant had been killed in March 1649 by Iroquois after a raid on a Huron village, Garnier knew he too might soon die.
