United Nations Group of Experts on Geographical Names (UNGEGN) is a permanent body of United Nations Economic and Social Council (ECOSOC). UNGEGN is one of the seven expert bodies of ECOSOC.

Some of the main goals of UNGEGN are to encourage national and international geographical names standardization, to promote the international dissemination of nationally standardized geographical names information and to adopt single romanization systems. UNGEGN's goal for every country is to decide on its own nationally standardized names through the creation of national names authorities or recognized administrative processes.

The United Nations Conference on the standardization of geographical names is held every five years. To make the work easier, UNGEGN Divisions have been formed. East Central and South-East Europe (ECSEE) Division is one of the 23 UNGEGN Divisions. The countries of the East Central and South-East Europe Division (ECSEED) are: Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Cyprus, Czech Republic, Georgia, Greece, Hungary, Montenegro, Poland, Serbia, Slovakia, Slovenia, The former Yugoslav Republic of Macedonia, Turkey and Ukraine.
