Antoinette Bourignon de la Porte (13 January 1616 – 30 October 1680) was a French-Flemish mystic and adventurer. She taught that the end times would come soon and that the Last Judgment would then be felled. Her belief was that she was chosen by God to restore true Christianity on earth and became the central figure of a spiritual network that extended beyond the borders of the Dutch Republic, including Holstein and Scotland. Bourignon's sect belonged to the spiritualist movements that have been characterized as the "third power".
