Kazimir

Meaning & origin

Kazimir is a Slavic name with a weighty, debated meaning that reflects its ancient roots. In the United States, it remains quite rare, ranking 3,757th in 2025 and given to just 1 in every 58,899 boys that year. The name has seen a steady rise since 2002, and it reached its highest recorded popularity in 2024, suggesting growing but still niche appeal. While it has no strong association with any particular state, its use trends in areas with Polish and Slavic heritage. As a name deeply tied to Eastern European history and culture, Kazimir offers a distinctive option for families honoring that background or drawn to strong, traditional names with a storied past.

Kazimir is a Slavic name derived from the elements kaziti (to destroy) and mir (peace, world), thus often interpreted as 'destroyer of peace' or alternately as 'one who commands peace' from kazati (to command). It has been borne by several Polish princes and saints, most notably Saint Casimir (1458-1484), the patron saint of Poland and Lithuania. The name has been used in various Slavic countries and was popularized in the West through figures such as the painter Kazimir Malevich.
