History & Origin

Marcos is the Spanish and Portuguese form of Marcus, the Latin name connected to Mars, Roman god of war. The name was widespread in the Roman Empire and entered Spanish through both Roman colonization and the influence of the Evangelist Mark (San Marcos), whose symbol — the winged lion — became the emblem of Venice.

Marcos is one of the most common boys' names in the Spanish-speaking world. In the United States it has been a consistent presence in Hispanic communities for generations. It charts regularly in U.S. rankings alongside Mark, Marco, and Marcus.

Did you know? The Gospel of Mark — whose author bears the same root name — is believed by many scholars to be the earliest of the four Gospels, making Marcus/Mark one of the foundational names of Western Christian tradition.
