The National Democratic Institute for International Affairs (NDI) is a nonprofit organization working to strengthen and expand democracy worldwide. Calling on a global network of volunteer experts, NDI provides practical assistance to civic and political leaders advancing democratic values, practices and institutions. NDI works with democrats in every region of the world to build political and civic organizations, safeguard elections, and to promote citizen participation, openness and accountability in government.

In many countries, advocates of democracy lack experience with democratic practices and face weakened or non-existent democratic institutions. They have turned to NDI for assistance in building their democratic structures. These include: national legislatures and local governments that function with openness and competence; broad-based political parties that are vehicles for public policy debates; and nonpartisan civic organizations that promote democratic values and citizen participation.
