Kazimier is Slavic in Origin.

Kazimier is a Slavic masculine given name, a streamlined/anglicized form of Polish Kazimierz and pan‑Slavic Kazimir, related to Latinized/Western Casimir. Its etymology traces to Slavic elements: kaziti “to harm/destroy” + mir “peace, world, prestige,” though a later learned reinterpretation links it to kazać “to declare/command,” yielding the preferred sense “one who proclaims peace” or “bringer of peace.”

Documented across Central and Eastern Europe, the name was borne by Polish royalty - Casimir III the Great and Casimir IV Jagiellon - and by Saint Casimir, patron of Poland and Lithuania, which helped spread it into Western usage. Variants include Kazimierz (Polish), Kazimir (Russian, Belarusian, South Slavic), Kazimír (Czech/Slovak), Casimir (English/French), Casimiro (Spanish/Italian/Portuguese), Kasimir (German/Scandinavian), and Kazimieras (Lithuanian). Feminine forms are Kazimiera and Casimira. Diminutives and short forms include Kazik, Kazio, and occasionally Kaz or Mir. In contemporary records, Kazimier appears chiefly in Polish‑diaspora contexts as a simplified or anglicized spelling.
