Agneta Wilhelmina Johanna van Marken-Matthes (4 October 1847 – 5 October 1909) was a Dutch entrepreneur. She and her husband were involved in the manufacture of yeast throughout their lives, and were engaged in the cooperative movement, taking care of their workers. Matthes and Van Marken created living quarters for workers in her hometown, Delft in South Holland, named Agnetapark after her. These are considered a model for the cooperative development and construction of garden cities (self-contained communities) for workers. Matthes founded and ran a Delft perfume factory, Maison Neuve, to take advantage of a by-product from the yeast factory.
