马其顿共和国（马其顿语：Република Македонија）是位于东南欧的巴尔干半岛南部的内陆小国，东临保加利亚，北临塞尔维亚，西临阿尔巴尼亚，南临希腊。由于希腊反对马其顿共和国使用“马其顿”的名称，世界上绝大多数国家以及联合国等国际组织现在均将该国暂时称为“前南斯拉夫马其顿共和国”（Поранешна Југословенска Република Македонија(ПЈРМ)/Poranešna Jugoslovenska Republika Makedonija(PJRM)）。目前全世界约有40个国家承认“马其顿共和国”本身使用的名称。
Macedonia (/ˌmæsɨˈdoʊniə/, Macedonian: Македонија), officially the Republic of Macedonia (Macedonian: Република Македонија, transliterated: Republika Makedonija [rɛˈpublika makɛˈdɔnija] ), is a country in the central Balkan peninsula in Southeastern Europe. It is one of the successor states of the former Yugoslavia, from which it declared independence in 1991. It became a member of the United Nations in 1993, but as a result of a dispute with Greece over its name, it was admitted under the provisional reference of the former Yugoslav Republic of Macedonia, sometimes abbreviated as FYROM.
A landlocked country, the Republic of Macedonia is bordered by Kosovo[a] to the northwest, Serbia to the northeast, Bulgaria to the east, Greece to the south and Albania to the west. The country's capital is Skopje, with 506,926 inhabitants according to a 2004 census. Other cities include Bitola, Kumanovo, Prilep, Tetovo, Ohrid, Veles, Štip, Kočani, Gostivar and Strumica. It has more than 50 lakes and sixteen mountains higher than 2,000 m (6,562 ft). Macedonia is a member of the UN and the Council of Europe. Since December 2005 it has also been a candidate for joining the European Union and has applied for NATO membership.
