The House of Hohenberg is an Austrian and Czech noble family that descends from Countess Sophie Chotek (1868–1914), who in 1900 married Archduke Francis Ferdinand of Austria-Este (1863–1914), the heir presumptive to the throne of the Austro-Hungarian Empire. As their marriage was a morganatic one, none of their children was in the line of succession to the Austro-Hungarian throne. Nevertheless, they represent the senior agnatic line of the House of Habsburg-Lorraine.

The head of the house bears the title of duke with the style of Highness, while all other members are titled as princes or princesses with the style of Serene Highness.

The House of Hohenberg was established by imperial decree of Emperor Francis Joseph of Austria when, upon the couple's marriage in 1900, he created Francis Ferdinand's wife Fürstin von Hohenberg (Princess of Hohenberg) in her own right with the style of Ihre fürstliche Gnaden (Her Princely Grace) and the specification that this title and style should also be borne by her descendants. In 1905, the Emperor granted Sophie and her descendants the higher style of Durchlaucht (Serene Highness).

In 1909, the Emperor raised Sophie to the more senior title of Herzogin von Hohenberg (Duchess of Hohenberg) with the superior style of Hoheit (Highness) and thereby changed the princely cap on her coat of arms to a duke's crown. Since that title had been granted ad personam, it expired upon Sophie's assassination in 1914.

In 1917, Emperor Charles of Austria granted the eldest son of Francis Ferdinand and Sophie the title of duke with the style of Highness. The other members of the family retained the title of prince or princess with the lesser style of Serene Highness. Thus, Maximilian became the first Duke of Hohenberg, with the dukedom being hereditary according to primogeniture in the male line. Following the collapse of the monarchy, the Austrian nobility, along with hereditary titles and such nobiliary particles as von, were abolished by law in 1919.

In 1938, several members of the family who were opposed to Adolf Hitler were arrested by the Nazis and sent to Dachau concentration camp, most notably Maximilian and his brother Ernst. Another former head of the family, Georg, served as ambassador of the Republic of Austria to the Holy See during part of the pontificate of Pope John Paul II. He was also a Knight of the Golden Fleece.

Members of the Hohenberg family are not only descended from, and married into, the House of Habsburg-Lorraine, but are also related through marriage to several other European dynasties, including the Grand Ducal Family of Luxembourg and the Princely Family of Liechtenstein. They also descend from King George II of Great Britain through his daughter Anne, Princess Royal and Princess of Orange, and are therefore distantly related to the British royal family.

The Hohenberg family still owns Artstetten Castle in Lower Austria, and parts of this castle are open to the public for visits. Former residences of the family include Konopiště château in Bohemia.

Artstetten Castle was selected to provide the main theme for an Austrian 10 euro commemorative coin, minted on 13 October 2004. The reverse shows the entrance to the crypt of the Hohenberg family. There are two portraits on the left, showing Archduke Francis Ferdinand and his wife Sophie, Duchess of Hohenberg.
