Louis Charles Félix François Gregh (16 March 1843 – 21 January 1915) was a French composer, conductor and music publisher.
As a composer, he wrote operettas, ballets, numerous popular songs, and over 150 works for piano for two, four, and six hands.
This was followed by the opera bouffe Le Présomptif which was premiered at the Royal Saint-Hubert Galleries in Brussels on 12 December 1883 followed by a staging at the Théâtre de la Renaissance in Paris in 1884.
His son Fernand Gregh (1873–1960) was a philosopher, literary critic and poet, member of the Académie française.
