'''Louis Lully''' (Paris, 4 August 1664 - 1 April 1734) was a French musician and the eldest son of Jean-Baptiste Lully.

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. For example, he collaborated with his brother Jean-Louis and Pierre Vignon on ''Zéphire et Flore'' (ballet, 1688), and with Marin Marais on ''Alcide'' (tragédie lyrique, 1693). The one work he composed on his own, ''Orphée'' (tragédie lyrique, 1690), was badly received when it was performed, though historians find it important for the prominence given in it to accompanied recitative .
