Sarajevo (Cyrillic: Сарајево) (pronounced [sǎrajɛʋɔ]) is the capital and largest city of Bosnia and Herzegovina, with an estimated population of over 311,161 people within its administrative limits. It is also the capital of the Federation of Bosnia and Herzegovina entity, as well as the center of the Sarajevo Canton, which has a population of 438,757. Nestled within the greater Sarajevo valley of Bosnia, it is surrounded by the Dinaric Alps and situated along the Miljacka River in the heart of Southeastern Europe and the Balkans.

Sarajevo is the leading social and cultural center of Bosnia and Herzegovina, and its region-wide influence in politics, education, entertainment, media, fashion, science, and the arts contribute to its status as Bosnia and Herzegovina's major economic center.

The city is historically famous for its traditional cultural and religious diversity, with adherents of Islam, Orthodoxy, Catholicism and Judaism coexisting there for centuries. Due to this long and rich history of religious and cultural variety, Sarajevo is often called the "Jerusalem of Europe" or "Jerusalem of the Balkans". It was, until recently in the 20th century, the only major European city to have a mosque, cathedral, Orthodox church and synagogue within the same neighborhood.
