Cosima is a feminine name of Greek origin, derived from kosmos meaning 'order, beauty, or universe'. It entered the U.S. naming records in 1985 and has remained uncommon, with a rank of 6,116 in 2025. Its peak popularity occurred in 2017, and since then its usage has been gradually declining. Cosima is most frequently chosen in California, reflecting its appeal among families with European heritage or an appreciation for classical names. The name carries a melodic, sophisticated quality without being overly familiar, making it a distinctive choice for parents seeking something elegant and historically rooted.
Cosima is the feminine form of Cosimo, which itself derives from the Greek name Kosmas (Κοσμᾶς), from kosmos (κόσμος), meaning 'order, decency, adornment' or 'universe'. The name was popularized in Italy by the Medici family, notably Cosimo de' Medici, and later spread to Germany and other European countries. It has been used in English-speaking countries since the 19th century, though it remains relatively rare.
