With a land area of 93,033 square kilometers, Hungary is a country in Central Europe. It measures about 250 kilometers from north to south and 524 kilometers from east to west. It has 2,258 kilometers of boundaries, shared with Austria to the west, Serbia, Croatia and Slovenia to the south and southwest, Romania to the southeast, Ukraine to the northeast, and Slovakia to the north.

Hungary's modern borders were first established after World War I when, by the terms of the Treaty of Trianon in 1920, it lost more than 71% of what had formerly been the Kingdom of Hungary, 58.5% of its population, and 32% of the Hungarians. The country secured some boundary revisions from 1938 to 1941: In 1938 the First Vienna Award gave back territory from Czechoslovakia, in 1939 Hungary occupied Carpatho-Ukraine. In 1940 the Second Vienna Award gave back Northern Transylvania and finally Hungary occupied the Bácska and Muraköz regions during the Invasion of Yugoslavia. However, Hungary lost these territories again with its defeat in World War II. After World War II, the Trianon boundaries were restored with a small revision that benefited Czechoslovakia.

Hungary ⁱ/ˈhʌŋɡəri/ (Hungarian: Magyarország [ˈmɒɟɒrorsaːɡ] ( listen)) is a country, which is located in Central Europe. It is situated in the Carpathian Basin and is bordered by Slovakia to the north, Ukraine and Romania to the east, Serbia and Croatia to the south, Slovenia to the southwest and Austria to the west. The country's capital, and largest city, is Budapest. Hungary is a member of the European Union, NATO, the OECD, the Visegrád Group, and is a Schengen state. The official language is Hungarian, also known as Magyar, which is part of the Finno-Ugric group and is the most widely spoken non-Indo-European language in Europe.

Following a Celt (after c. 450 BC) and a Roman (AD 9 - c. 430) period, the foundation of Hungary was laid in the late 9th century by the Hungarian prince Árpád, whose great-grandson Saint Stephen I was crowned with a crown sent by the pope from Rome in 1000 AD. The Kingdom of Hungary lasted for 946 years, and at various points was regarded as one of the cultural centres of the Western world. After about 150 years of partial Ottoman occupation (1541–1699), Hungary was integrated into the Habsburg Monarchy, and later constituted half of the Austro-Hungarian dual monarchy (1867–1918).
