Louis François Dauprat (24 May 1781 in Paris – 16 July 1868 in Paris) was a French horn player, composer and music professor at the Conservatoire de Paris. He played and taught only natural horn, but was also very interested in the first experiments with keyed horns. He successfully ensured the development of a distinctively French school of playing, marginally influenced by the invention of the valve horn.
