Justas is of Lithuanian origin and means "just, fair". It's composed of the elements 'jus' meaning 'law', 'right', 'justice', and 'tas', meaning 'that'. Therefore, Justas can be interpreted as 'the one who is just' or 'one who upholds justice'. It was initially used in Lithuania but has since gained global recognition. The name Justas is associated with concepts of fairness, impartiality, and integrity.
Justas is quite rare; there were only 5 babies named Justas born each year from 1999 onwards.
