Meaning & origin

Marcos has been in continuous use in the United States since 1888, when it first appeared in Social Security records. Its popularity peaked in 2001, and since 2000 it has been on a gentle decline, reflecting broader trends away from traditional names in favor of more modern coinages. As of 2025, the name sits at rank 516, with about 1 in every 2,950 newborn boys named Marcos. Geographically, the name is most common in Nebraska, New Mexico, and California, states with significant Hispanic populations. It remains a familiar and widely respected name across Spanish- and Portuguese-speaking communities, though its usage is now less frequent than in the early 2000s.

Marcos is the Spanish and Portuguese form of Marcus, a Latin personal name derived from Mars, the Roman god of war. The name was borne by several early saints, including the Evangelist Saint Mark, whose Latin name was Marcus. It has been common in the Spanish- and Portuguese-speaking world for centuries, often used in honor of Saint Mark.
