Meaning & origin

Casimira is a rare and distinctive name of Slavic origin, the feminine counterpart to Casimir. It first appeared in U.S. records in 1896, which was also its peak year for usage, though it has never achieved widespread popularity. As of 2025, it remains outside the top 1000 names, with no recorded rank or measurable frequency (1-in-N data). The name has been borne by families with Polish heritage, reflecting a tradition of naming girls after male saints via feminine forms. Its trajectory is classified as stable, indicating consistent but very low usage over time. Despite its obscurity, Casimira carries a robust history and a strong, layered meaning that appeals to those seeking an uncommon name with deep European roots.

Casimira is the feminine form of Casimir, derived from the Slavic elements kaziti 'to destroy' and mir 'peace'. The name was borne by several Polish saints and royalty, notably Saint Casimir (1458-1484), patron of Lithuania and Poland. Its use in the United States has been rare, primarily among families of Polish or Slavic descent.
