Marc is the French and Catalan form of Mark, from the Latin Marcus, a name most likely derived from Mars, the Roman god of war, and so read as "dedicated to Mars" or "warlike". The gospel writer Saint Mark spread the name through the Christian world. In the United States Marc was a solid choice at number 229 in 2000, dropped out of the top 1000 in 2020 and ranks number 1,237 in 2025.
