Alexandre Charles Lecocq (3 June 1832 – 24 October 1918) was a French composer, known for his opérettes and opéras comiques. He became the most prominent successor to Jacques Offenbach in this sphere, and enjoyed considerable success in the 1870s and early 1880s, before the changing musical fashions of the late 19th century made his style of composition less popular. His few serious works include the opera Plutus (1886), which was not a success, and the ballet Le cygne (1899). His only piece to survive in the regular modern operatic repertory is his 1872 opéra comique La fille de Madame Angot (Mme Angot's Daughter). Others of his more than forty stage works receive occasional revivals.
