Bosnia and Herzegovina, abbreviated BiH or B&H, sometimes called Bosnia–Herzegovina and often known informally as Bosnia, is a country at the crossroads of south and southeast Europe, located in the Balkans.

The capital and largest city is Sarajevo. Bosnia and Herzegovina borders Serbia to the east, Montenegro to the southeast, and Croatia to the north and southwest.

Today, the country is home to three main ethnic groups, designated “constituent peoples” in the country’s constitution. The Bosniaks are the largest group of the three, the Serbs are the second-largest, and the Croats are the third-largest. In English, all natives of Bosnia and Herzegovina, regardless of ethnicity, are called Bosnian. Minorities, who under the constitution are categorized as "others", include Jews, Roma, Albanians, Montenegrins, Ukrainians and Turks.

Bosnia's constitution does not specify any official languages. However, academics Hilary Footitt and Michael Kelly note the Dayton Agreement states it is "done in Bosnian, Croatian, English and Serbian", and they describe this as the "de facto recognition of three official languages" at the state level.
