Hermann Kern (14 March 1838 – 18 January 1912) was an Austrian painter.
He was born in Liptóújvár, former Kingdom of Hungary, now Liptovský Hrádok, Slovakia. His father recognized his exceptional talent at an early age and paid for his education. At the age of 16 he began his artistic training in Levoča. He went to Prague in 1854, where he studied under J.B. Klemens, and then attended the Academy of Fine Arts in Vienna. In 1867 he studied in Düsseldorf, and in 1870 he studied at the Academy of Fine Arts in Munich.
He worked initially in Budapest as a portrait and genre painter. Later, he moved to Paris. In 1877 he moved to Vienna, and lived there with his large family (his wife Paulina and 10 children) as an emperor Franz Joseph I court painter until his death in 1912 in Austria.
Kern specialized in portraits and genre scenes. The latter often depicted children at play, music making gypsies, tavern scenes, and single persons. In 1885 he painted the ceiling decoration of the Szeged Theatre.
