Van Voorst tot Voorst is an old Dutch noble family from the Dutch province Overijssel.
The first documented ancestor is Fredericus van Hekeren van der Ese (in 1295) who was an adviser to Reginald II of Guelders. The surname van Voorst entered the family in the 14th century when one of his descendants married Lutgardis van Voorst, whose ancestors owned the castle Voorst near Zwolle, Overijssel. The counts of van Rechteren are also descendants of this couple.
During the twentieth century, the family produced several high ranking officers of the Dutch army, Commissioners of the Queen, diplomats and members of the House of Representatives and Senate. Members carry the title of baron.
