Heinrich Ludwig Egmont Dorn (14 November 1800[1] or 1804 – 10 January 1892) was a German conductor, composer, teacher, and journalist.

Later, he studied in Berlin with Ludwig Berger, Bernhard Klein, and Carl Friedrich Zelter.

Dorn became well known as a conductor of opera, and held theatre posts at Königsberg (1828), Leipzig (1829–32), Hamburg (1832), Riga (1834–43), and Cologne (1844–8).

In 1849, he became co-conductor, with Wilhelm Taubert, of the Berlin Hofoper - a post he held until 1869.

He was a harsh critic of Richard Wagner but was persuaded to conduct the opera Tannhäuser, in 1855.
