Kassius

Meaning & origin

Kassius is a modern variant spelling of the ancient Roman name Cassius. While the original Cassius has been in use for centuries, the K-spelling first appeared in the United States in 2001 and has remained a relatively uncommon choice. Its popularity peaked in 2022, after which it began a slight decline. In the most recent year available (2025), Kassius ranked 2230th, with about 1 in every 27,112 boys receiving the name. The name is most common in the southern states, particularly Florida and California. The variant spelling with a 'K' gives the name a contemporary, edgy feel compared to its traditional counterpart. Parents may be drawn to its strong, distinctive sound and its connection to both Roman history and modern naming trends.

Kassius is a modern respelling of the ancient Roman name Cassius. The Roman nomen Cassius is of uncertain origin but is frequently linked to the Latin word 'cassus', meaning 'hollow' or 'empty'. The name Cassius has been used in the English-speaking world since the 17th century, partly due to its appearance in the works of Shakespeare (Julius Caesar) and the Bible (the New Testament). The variant Kassius (with a K) arose in the early 2000s, likely influenced by the popularity of names beginning with 'K' and the fashionable sound of surnames as first names.
