Joost is a male Dutch first name. It derives from the name Jodocus which can ultimately be traced back to St. Judoc a Breton saint in the seventh century: Jodocus → Josse → Joos → Joost (the addition of an end-t is a peculiarity of the Dutch language especially some local dialects). Sometimes an alternative derivation from the Ancient Roman name Justus is suggested. In Dutch proper it is pronounced [ˈjoːst]. In Afrikaans it is pronounced [ˈjust].
