Meaning & origin

Kosta entered U.S. records in 1960 and has seen gradual growth, particularly since 2000. In 2025, it ranked 7,679 with a 1-in-170,808 incidence rate, reflecting its uncommon but steady use. The name reached its peak popularity in 2022, suggesting a growing interest in this concise, Greek-derived alternative to the more common Constantine or Kostas. While not yet found in any top state preference lists, its steady upward trajectory since the turn of the millennium indicates a slow but consistent rise in awareness, likely fueled by parents seeking a short, distinctive name with a solid historical foundation. The name's trajectory aligns with the broader trend of reviving classic European short forms in the United States.

Kosta is a short form or variant of Constantine, itself derived from the Latin Constantinus, meaning 'constant' or 'steadfast'. The name has been used across Eastern Europe and the Balkans, especially in Greek and Slavic contexts, often as a diminutive of names like Konstantinos or Kostadin. It has seen modest use in the United States beginning in the mid-20th century.
