Kasia

An attractive and intriguing choice with an appealing blend of gentle and sharper sounds, Kasia is a diminutive of Katarzyna, the Polish form of Katherine. Ultimately from Greek, it is generally interpreted to mean "pure".

Notable bearers include actress Kasia Smutniak, singer Kasia Kowalska, cyclist Kasia Niewiadoma, TV presenter Kasia Madera, singer Kasia Cerekwicka, influencer Kasia Vuorinen, writer Kasia Delgado, and singer Kasia Stankiewicz.

In addition to its Polish roots, Kasia may also be used as a Greek variation of the Biblical Keziah, meaning "cinnamon, cassia"; as a spelling twist on Cassia, a name that may relate to Keziah, or be a form of Cassius; and as a play on Acacia, a tree name, inspired by the Akacia or Akasia spelling.

The pronunciation may therefore vary. In Greek KA-sya may be heard, but as a spin of Cassia, it could she KA-see-uh or KASH-uh. As a twist on Acacia, it may be more like KAY-shuh or KAY-see-uh.

Pronounced KAH-shuh.

As of October 2026, Kasia ranked #5481 in US births in 2025 SSA, peaked at #2296 in 2002.
