The Park Slope Food Coop (PSFC) is a food cooperative located in the Park Slope neighborhood of Brooklyn in New York City. It is one of the oldest and largest active food co-ops in the United States. As a food cooperative, one of its goals is to be a "buying agent to its members, not a selling agent to any industry." Non-members are welcome to visit the store, but may not shop. Formed in 1973, PSFC has grown to include over 17,000 members.
