Prince Joseph Franz Karl von Lobkowicz (17 February 1803 – 18 March 1875) was an Austrian nobleman who served as Head of Household of the Empress Elisabeth of Austria.

He was a youngers son, of twelve children, born to Joseph Franz, 7th Prince of Lobkowitz (1772–1816) and Princess Maria Karolina von Schwarzenberg (1775–1816).

[5] As he was just one of many sons, the family estates were divided amongst the brothers, thereby creating several new subsidiary lines with Prince Johann Nepomuk founding the line of Křinice, Prince Ludwig Johann founding a line in Hungary, and Prince Karl Johann serving as Governor of Lower Austria, Moravia, and of Tyrol.

[5] Prince Joseph Franz, who served as Head of Household of the Empress Elisabeth founded the line of Dolní Beřkovice near the old Lobkowicz land in north-central Bohemia, located on the Elbe river.
