Kassius is Latin in Origin.

Kassius is a modern K-initial variant of Cassius, the ancient Roman nomen borne by a prominent gens. The name likely derives from Latin cassus, “empty” or “hollow,” though scholars also propose an Etruscan origin with unknown meaning. The spelling with K reflects contemporary tastes and Germanic/Scandinavian transliteration habits, while keeping the classical cadence.

In antiquity, figures such as Gaius Cassius Longinus, one of Julius Caesar’s assassins, and the historian Cassius Dio carried the name, and several early saints preserved it in Christian use. Today, Kassius appears as a fresh update alongside established forms. Related variants include Cassius (standard Latin), Casius, Cássio (Portuguese), Cassio (Italian), and the derivatives Cassian/Cassiano. Short forms and nicknames span Cass, Cash, and Kass. Usage has inched upward in the Anglophone world through pop-culture visibility while retaining an unmistakably classical feel.
