An imperial crown is a crown worn by an emperor. In the European cultural area, it also symbolizes the power of the empire in heraldic depictions. The craftsmanship corresponded to the king's crown, with precious stones and pearls set into the precious metal frame for decoration. Their external form differed from crowns of the same period and the same reign. The use of Christian symbols to emphasize the divine rule of the emperor is the reason for the deviation.

The Imperial Crown of Austria is a crown formerly in use by the monarchs of the Habsburg monarchy. The crown was originally made in 1602 in Prague by Jan Vermeyen as the personal crown of Holy Roman Emperor Rudolf II, and therefore is also known as the Crown of Emperor Rudolf II. The crown was used as a private crown of the Holy Roman Emperors and Kings of Hungary and Bohemia from the House of Habsburg. In 1804 it became the official crown of the newly constituted Austrian Empire. After 1867 it remained the imperial crown of the Cisleithanian part of the Austro-Hungarian Empire until 1918.
