Meaning & origin
Marcio is the Portuguese form of the Latin family name Marcius, which traces back to the Roman god Mars. Though familiar in Brazil and Portugal, it has never been widely used in the United States. The name first appeared in U.S. records in 1970 and reached its highest rank of 3,530 in 1986, when it was given to roughly 1 in 42,000 newborn boys. Since then, usage has declined steadily; by 2025, it had fallen to rank 10,695, with an occurrence rate of 1 in 284,679. Marcio has never been concentrated in any particular state, and its trajectory has been stable in recent decades. It remains a distinctive choice for families with Portuguese heritage or those seeking a name with classical Roman roots.
Marcio is the Portuguese form of the Latin name Marcius, a Roman family name derived from Marcus, which itself comes from Mars, the Roman god of war. The name was borne by several early saints and has been used in Portuguese-speaking countries since medieval times, though it remains less common than its English counterpart Marcius or the Spanish Marcio.
