Wikimedia chapters are independent organizations founded to support and promote the Wikimedia projects within a specified geographical region (country). Like the Wikimedia Foundation, they aim to "empower and engage people around the world to collect and develop educational content under a free license or in the public domain, and to disseminate it effectively and globally". 39 chapters currently exist, with at least one Chapter on every continent of the world (except Antarctica).
