The country known as the Republic of Macedonia renames itself the Republic of North Macedonia in accordance with the Prespa agreement, settling a long-standing naming dispute with Greece.

North Macedonia, officially the Republic of North Macedonia, is a landlocked country in Southeast Europe. It shares land borders with Greece to the south, Albania to the west, Bulgaria to the east, Kosovo to the northwest and Serbia to the north. It constitutes approximately the northern third of the larger geographical region of Macedonia. Skopje, the capital and largest city, is home to a quarter of the country's population of over 1.83 million. The majority of the residents are ethnic Macedonians, a South Slavic people. Albanians form a significant minority at around 25%, followed by Turks, Roma, Serbs, Bosniaks, Aromanians and a few other minorities.

The Prespa Agreement, also known as the Treaty of Prespa, the Prespes deal or the Prespa accord, is an agreement reached in 2018 between Greece and the then-Republic of Macedonia, under the auspices of the United Nations, resolving a long-standing naming dispute between the two countries. Apart from resolving the terminological differences, the agreement also covers areas of cooperation between the two countries in order to establish a strategic partnership.

The use of the country name "Macedonia" was disputed between Greece and the Republic of Macedonia between 1991 and 2019. The dispute was a source of instability in the Western Balkans for 25 years. It was resolved through negotiations between the two countries, mediated by the United Nations, resulting in the Prespa Agreement, which was signed on 17 June 2018. Pertinent to its background is an early 20th-century multifaceted dispute and armed conflict that formed part of the background to the Balkan Wars. The specific naming dispute, although an existing issue in Yugoslav–Greek relations since World War II, was reignited after the breakup of Yugoslavia and the newly-gained independence of the former Socialist Republic of Macedonia in 1991. Since then, it was an ongoing issue in bilateral and international relations until it was settled with the Prespa agreement in June 2018, the subsequent ratification by the Macedonian and Greek parliaments in late 2018 and early 2019 respectively, and the official renaming of Macedonia to North Macedonia in February 2019.
