Barbara Heinemann Landmann (January 11, 1795 – May 21, 1883) was a spiritual leader with the Community of True Inspiration, for which she served as Werkzeug, or Instrument, in both Europe and the United States.
In 1817, at age 22, she experienced a religious vision and joined the Community of True Inspiration (Scheuner, 1873).
After settling in the present-day West Seneca, New York, Landmann again became a Werkzeug with the Ebenezer Colonies in the area.
In that year she moved with some followers to Homestead, Iowa and started another congregation of Inspirationists known as the Amana Colonies.
Landmann's work with the Amana Colonies in Iowa was noted by author Charles Nordhoff in the book The Communistic Societies of the United States (1875).
