Cassian
/ˈkæʃ.ən/
Cassian derives from the Roman family name Cassius, possibly connected to the Latin cassus meaning “hempty” or “hollow.” The -ian suffix marks it as an adjectival or derived form.
Saint John Cassian (c. 360-435) was a Christian monk who founded an important monastery at Marseilles and wrote influential works on monastic life that shaped both Eastern and Western monasticism.
Cassian peaked at No. 531 in 2023 with 555 births. In 2024 it ranks No. 616 with 462 births, one year after its recent high.
What the name Cassian means
The character Cassian Andor from Disney’s Rogue One: A Star Wars Story (2016) and the series Andor (2022) brought the name to a huge new audience.
Three syllables—KAS-ee-un—have a classical, unhurried rhythm. The double-s interior and the -ian ending give it the feel of an ancient Roman cognomen.
Parents choosing Cassian often want the classical elegance of Cassius with a softer, more approachable ending that avoids the sharp finality of the -us form.
It sits between Cassius (bold, Roman) and Caspian (fictional, literary)—offering genuinely historical roots with the phonetic appeal of both neighbors.
