Soros foundations are autonomous institutions established in particular countries or regions to initiate and support open society activities. The priorities and specific activities of each Soros foundation are determined by a local board of directors and staff in consultation with George Soros and OSI boards and advisors. In addition to support from the Open Society Institute, many of the foundations receive funding from other sources.

Soros foundations consist of national foundations in 29 countries, foundations in Kosovo and Montenegro, and two regional foundations, the Open Society Initiative for Southern Africa (OSISA) and the Open Society Initiative for West Africa (OSIWA). OSISA and OSIWA, which are governed by their own boards of directors and staffs from the region, make grants in a total of 27 African countries.

OSI's work in Russia—including that of the local Soros foundation—is currently being reorganized.
