Acorn is a farm-based, anarchist, egalitarian, intentional community located in rural Louisa County, Virginia, United States. It is a member of the Federation of Egalitarian Communities. Acorn was started in 1993 as a spin-off community of the older, larger Twin Oaks Community. In the early 1990s, the Twin Oaks population filled to capacity, with many more people who still wished to join. The increase of people put pressure on the community, eventually having the founding of Acorn by Twin Oaks members on a 75-acre farm 7 miles away from Twin Oaks.

Group meetings are held weekly and decisions are reached through consensus. Many members, and the community in general, encourage environmental awareness, therefore they strive to live lightly on the land. Although structured in areas such as membership, policies are kept to a minimum; it is preferred that calm anarchy prevail. Of the policies that are in place, the culture encourages personal responsibility rather than supervision. The community takes on issues on a case-by-case basis, keeping in mind that needs are varied among individuals.

Both the population and stability of Acorn have fluctuated significantly in its relatively short history.

Acorn supports itself through its non-GMO heirloom seed business, Southern Exposure Seed Exchange. The income from this business is held in common and used to support Acorn's members, as well as a number of other activities (such as maintenance of a fund to support the formation of other cooperative egalitarian communities).

All members have full medical, dental, and optical care, as well as a monthly stipend.

Acorn has a highly flexible self-directed labor system in keeping with its philosophy of non-hierarchy and personal independence coupled with personal responsibility. The work of the seed business is done by a dynamic and flexible collection of members and guests who attend to the necessary work tasks based on the varying needs of the business as well as the abilities and inclinations of the participants. Being non-hierarchical, there are no bosses, owners, investors, managers, or supervisors to direct the work. Therefore, work occurs with minimal supervision. Priorities are identified, and results are achieved, by the input of those participants who have the most insight into what is required for the task to be done; this is coupled with the agreement and assumption of responsibility of the other participants.

The farm works in large part due to the fact that the community carefully chooses who becomes a member by a process called Clearness. After spending three weeks visiting the community, prospective members get "clear" with every single member of the community by meeting individually for in-depth conversations. Then all members meet to decide whether or not to accept that person as a provisional member. The decision, like all decisions at Acorn, is made through consensus.

Once accepted, a person remains a provisional member for one year and then the full members decide whether or not to accept that person into full membership. Provisional membership is a trial membership and that person remains at Acorn so long as that person has the consent of members to be there. If at any time consent is withdrawn that person must leave. Once that person is accepted as a full member, a consensus is required for the community to require that person to leave.

Members of Acorn are involved in various community service activities. These include Plant a Row (which grows food for local food pantries serving local disadvantaged persons) and Food Not Bombs. The community also supports members who wish to pursue activism, especially as it relates to food safety and blocking the spread of GMOs including the March Against Monsanto.

Acorn has a minimum work quota of 42 hours a week, which all adult members are expected to meet. This is the minimum amount of work deemed acceptable, with most members working well over this amount.

All work done by members is equally creditable. Almost anything that needs to be done is considered work. This includes traditionally recognized work such as office work, maintenance, and farming. However, less traditionally recognized work such as childcare, cooking, cleaning, and preparing for communal parties are equally labor creditable. As a result of this system, members feel they have significantly more free time than when they were working regular jobs. Based upon meeting the minimum amount of work expected, members enjoy four weeks of vacation per year. By working over the expected quota members can accumulate additional vacation time.

The labor system at Acorn is quite unstructured. However, this does not mean members simply do whatever they want and call it work. Keeping in mind the needs and goals of the community, as well as engaging in group and individual conversations, members identify and decide on relevant tasks that need to be accomplished. Individuals then step forward to take on the responsibility of accomplishing the work in a timely fashion.

Acorn, with 82 other farmers and seed businesses, preemptively sued Monsanto Corporation to protect themselves from predatory lawsuits for GMO patent infringement. This suit is between Organic Seed Growers and Trade Association and Monsanto. This class action suit was litigated by the Public Patent Foundation in response to Monsanto's multiple lawsuits against farmers who have been contaminated by their GMO seeds.

Living is communal rather than individuals living in their own houses. Each member is provided with their own bedroom in one of the four living structures.

In 2013, the construction of a new building began as a source of new space for the seed farm. The building has a significant number of environmentally friendly features which include low-impact building materials, significant southern exposure, passive ventilation for cooling, timber-frame construction technique, and desiccant air conditioning for maintaining stored seed temperatures. The estimated completion is Fall of 2014.
