Joost

Joost is a Dutch masculine given name derived from the Latin Iustus, meaning just or righteous. It developed as a regional Low Countries form of the name that spread across medieval Europe through Christian usage, honoring the virtue of justice as a personal quality. The Flemish playwright Joost van den Vondel, a towering figure of Dutch Golden Age literature, is among the most celebrated bearers of the name. Related forms include Just, Justin, and Justus.
