Baron Herman Severin Løvenskiold (30 July 1815 – 5 December 1870) was a Norwegian composer, most noted for his score for August Bournonville's 1836 version of the ballet La Sylphide for the Royal Danish Ballet in Copenhagen.
Herman Severin Løvenskiold was born at Ulefoss in the municipality Nome, Norway. He was the son of Eggert Christopher Løvenskiold (1788–1861), director Ulefos Jernværk. In 1829, his family moved to Denmark. He was trained in music by composer Peter Casper Krossing. He also went abroad where he studied in Vienna, Leipzig and St. Petersburg. Following his return to Denmark, he composed music for a number of dramatic works at the Royal Danish Theatre. From 1851, he was the organist at Christiansborg Castle Church (Christiansborg Slotskirke) on Slotsholmen in Copenhagen. This church, which dated from 1738-1742, was frequently attended by members of the Danish Royal Family.
