Brook Farm, also called the Brook Farm Institute of Agriculture and Education or the Brook Farm Association for Industry and Education, was a utopian experiment in communal living in the United States in the 1840s. It was founded by former Unitarian minister George Ripley and his wife Sophia Ripley at the Ellis Farm in West Roxbury, Massachusetts in 1841 and was inspired in part by the ideals of Transcendentalism, a religious and cultural philosophy based in New England. Founded as a joint stock company, it promised its participants a portion of the profits from the farm in exchange for performing an equal share of the work. Brook Farmers believed that by sharing the workload, ample time would be available for leisure activities and intellectual pursuits.

Life on Brook Farm was based on balancing labor and leisure while working together for the benefit of the greater community. Each member could choose to do whatever work they found most appealing and all were paid equally, including women. Revenue for the community came from farming and from selling hand-made products like clothing as well as through fees paid by the many visitors to Brook Farm. The main source of income was the school, which was overseen by Mrs. Ripley. A pre-school, primary school, and a college preparatory school attracted children internationally and each child was charged for his or her education. Adult education was also offered.
