Justa is the feminine given name from Latin Iusta, derived from iustus "just, upright, equitable." The switch from classical I- to J- reflects later Romance and ecclesiastical spelling, and the name has long carried connotations of fairness, righteousness, and lawful conduct.

It was borne by early Christian martyrs, most notably Santa Justa of Seville paired with Saint Rufina in the 3rd century, whose cult secured the name's prominence in medieval and early modern Iberia and parts of the western Mediterranean. Usage survives in Spain, Portugal, and Latin America, often with religious or family continuity, while it remains rare in English-speaking countries. Documented variants and cognates include Iusta (Latin), Justa (Spanish/Portuguese/Catalan), Giusta (Italian), and extended forms Justina/Justine/Giustina; Spanish nicknames such as Justi occur. The meaning consistently centers on justice, integrity, and moral rectitude.
