Prince Johann Nepomuk Karl Philipp von Lobkowicz (14 January 1799 – 6 June 1878) was a Bohemian nobleman.

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

[6] As the second-born of the older princely line of the Lobkowicz family, Johann inherited the Týnec nad Sázavou porcelain factory.

Established in 1793 within the castle and brewery at Týnec nad Sázavou, this factory became renowned for its high-quality porcelain production.

His seat, Křimice Castle, on the outskirts of Plzeň, was acquired by his wife's family in the 17th century and rebuilt in the classical style in 1811.
