Casimir Origin and Meaning

The name Casimir is a boy's name of Polish origin meaning "destroyer of peace".

Casimir, a traditional name of Polish kings, could do quite well these days as we see the rise of Caspian, Cassius, Castiel, et. al. Like Leopold and Laszlo, Casimir is strong and worth considering if you've got an adventurous streak — and bet your son will too.

An alternative commonly cited meaning that modern parents might prefer is "proclaimer of peace". The traditional Polish version of the name is Kazimierz.
