Louis Lully (4 August 1664 in Paris – 1 April 1734) was a French musician and the eldest son of Jean-Baptiste Lully.
Louis Lully was the second child (after Catherine-Madeleine Lully) and eldest son of Jean-Baptiste Lully and his wife Madeleine Lambert.
He married Marthe Bourgeois on 27 December 1694, in St.
Martial de Paris, "with the tacit and verbal consent of Madeleine Lambert, his mother, to whom a summons had been made".
The son survived Louis Lully by only a little over a year, dying in Paris on 21 July 1735 (Courtaux 1900, col 313–14).
Nearly disinherited by his father following dissolute behaviour and imprisonment, Louis did not have the brilliant career anticipated for him, not only because of his behaviour but also due to his lack of talent.
What success he had as an opera composer was mostly down to works written in collaboration with others.
