Cassius is Latin in Origin.
Cassius is a Latin nomen from the ancient Roman gens Cassia, likely of Etruscan origin and thus of uncertain meaning. A traditional Latin derivation links it to cassus, “hollow/empty,” though scholars often view this as folk etymology. Related forms include the feminine Cassia and the later Cassian (from Cassianus).
The name is well attested in Roman history - most famously Gaius Cassius Longinus, a leading conspirator in Julius Caesar’s assassination, and the historian Cassius Dio. It appears in Christian calendars with several saints named Cassius, and in English literature through Shakespeare’s Julius Caesar. Usage in the Anglosphere revived in the 19th–20th centuries via U.S. abolitionist Cassius Marcellus Clay and his namesake, the boxer born Cassius Clay (Muhammad Ali). International variants include Cássio/Cassio (Portuguese/Italian), Cassien (French, via Cassianus), Kassius (German), and Kasjusz (Polish); diminutives include Cass and Cash.
