Bückeburg (German pronunciation: [ˈbʏkəbʊʁk]; Northern Low Saxon: Bückeborg) is a town in Lower Saxony, Germany, on the border with North Rhine Westphalia.

Built in 1915 in Neo-Romanic style and resembling the Roman Pantheon, it is the world's largest private sepulchre still in use.

In the period around 1950 when the Royal Air Force had a base nearby, the children of the service families attended a school in the Schloss.

It is known for its pulpit and especially for the ornately decorated bronze-cast font, made by the Dutch artist Adriaen de Vries.

Bach set several texts by Johann Gottfried Herder, who was at the Bückeburg court as its superintendent and chief preacher from 1771–1776.
