Karolius is Latin in Origin.

Karolius is a Lithuanian masculine name, a Latinizing variant of Karolis that ultimately descends from the Proto-Germanic Karl, meaning ‘man; free man’. The form aligns with medieval Latin Carolus/Karolus used in ecclesiastical records, with -ius matching Lithuanian masculine morphology seen in names like Paulius and Marius. Its meaning centers on personal freedom and manhood, inherited through the widespread Charles/Karl family of names.

Usage clusters in early modern and 19th- and early 20th-century baptismal registers of the Polish-Lithuanian cultural sphere, where scribes alternated between Karolus, Karolius, and Karolis. While today Karolis is standard in Lithuania, Karolius survives as a rare, archival or stylistic choice. International cognates include Karl/Carl (German/Scandinavian), Charles (English/French), Carlo (Italian), Carlos (Spanish/Portuguese), Karel (Czech/Dutch), Karol (Polish/Slovak), and Károly (Hungarian). Related Lithuanian forms: Karolis; affectionate diminutives sometimes follow native patterns in -ukas or -ėlis.
