Louis Spohr (1784 – 1859) was a German violinist, composer, and conductor whose compositions illustrate an early aspect of the Romantic period in German music.

Spohr taught himself composition by studying the scores of Wolfgang Amadeus Mozart. He studied violin with the leader of the Brunswick orchestra and in 1802 with Franz Eck, who took him on a tour of Russia. He toured Italy with the great violin virtuoso Niccolò Paganini and in 1817 became conductor of the opera in Frankfurt am Main. In 1820 Spohr made the first of his six tours of England. He became court conductor at Kassel in 1821. In his later years his political radicalism incurred the displeasure of his patron, the elector of Hesse-Kassel, who pensioned him in 1857. Shortly afterward, he broke his left arm and was no longer able to play the violin.
