The House of Lobkowicz is a Czech noble family that dates back to the 14th century and is one of the oldest Bohemian noble families. The family also belongs to the German, Austrian and Belgian nobility. The first Lobkowiczs were members of the gentry of north-eastern Bohemia in the late 14th century. The family's Imperial immediacy over Princely county of Störnstein was mediatized by Bavaria in 1807. As such, the House of Lobkowicz belong to the small group of families that constitute the Hochadel and is one of the mediatised houses.

Czech nobility consists of the noble families from historical Czech lands, especially in their narrow sense, i.e. nobility of Bohemia proper, Moravia and Austrian Silesia – whether these families originated from those countries or moved into them through the centuries. These are connected with the history of Great Moravia, Duchy of Bohemia, later Kingdom of Bohemia, Margraviate of Moravia, the Duchies of Silesia and the Crown of Bohemia, the constitutional predecessor state of the modern-day Czech Republic.
