Casia is a streamlined form of Cassia, ultimately from Latin casia and Greek kassia, the aromatic cassia/cinnamon bark; the word itself likely traces to Hebrew qetsi'ah. The name can also reflect the feminine of the Roman family name Cassius (gens Cassia), sometimes linked to Latin cassus, meaning hollow or empty, giving Casia a dual heritage of spice and classical lineage.

Use appears in Late Antiquity through the Middle Ages, especially in Byzantium via the celebrated 9th-century poet-hymnographer Kassia (Kassiani).
