Cesarion is Greek, Latin in Origin.

Cesarion derives from Greek Kaisarion (Καισαρίων), the affectionate diminutive of the Latin cognomen Caesar, built with the Greek -ion suffix. Its core sense is “little Caesar,” often understood as “young/son of Caesar” or “belonging to Caesar.” Because Caesar later became an imperial title that yielded forms like Kaiser and Tsar, Cesarion uniquely preserves the intimate, youthful nuance rather than the titular one. The ultimate origin of Caesar is debated - possibly from caesaries “hair,” a Punic word for “elephant,” or caedere “to cut” - but the diminutive’s meaning is clear.

Historically, the name is inseparable from Ptolemy XV Philopator Philometor Caesar (47–30 BCE), the child of Julius Caesar and Cleopatra VII, popularly called Caesarion, the last Pharaoh of Egypt. It remained rare afterward, reappearing mainly in scholarship and literature (notably C. P. Cavafy’s “Kaisarion”). Variants and spellings include Caesarion, Kaisarion, Kesarion, and Cezarion; related names from the same root include Caesar, César, Cesare, and Cesario.
