Meaning & origin
Cosme is a rare Iberian form of the ancient Greek name Kosmas. The name is historically tied to Saint Cosmas, a 3rd-century martyr. In modern U.S. data, Cosme has never been common, ranking 6,803 in 2025, with an occurrence rate of 1 in 142,340 births. Its peak year was its first recorded year, 1909, and it has been on a falling trajectory since 1994. The name remains almost exclusively used within Spanish- and Portuguese-speaking communities.
Cosme is the Spanish and Portuguese form of Cosmas, a Greek name stemming from kosmos, "order, ornament, universe." The name was borne by Saint Cosmas, a 3rd-century martyr and physician often paired with his twin brother Damian. The cult of these saints spread across Europe, and Cosme became established in Iberian naming traditions.
