History & Origin

Demario belongs to the De- composition school of African American naming, here built on Mario — the Italian and Spanish form of Roman Marius, traditionally linked to Mars. It rose through the 1980s and 90s beside Demarcus and Demarco.

Singer Demario-generation R&B and a steady line of football rosters keep it current. It remains uncommon — four syllables that drum.

Did you know? Mario descends from Roman Marius — a clan name tied to Mars — meaning every Demario, like every video-game Mario, carries the god of war in casual clothes.
