Madama Butterfly (IPA: [maˈdaːma ˈbatterflai]; Madame Butterfly) is an opera in three acts (originally two) by Giacomo Puccini, with an Italian libretto by Luigi Illica and Giuseppe Giacosa. The opera is based in part on the short story "Madame Butterfly" (1898) by John Luther Long, which in turn was based partially on stories told to Long by his sister Jennie Correll and partially on the semi-autobiographical 1887 French novel Madame Chrysanthème by Pierre Loti. Long's version was dramatized by David Belasco as a one-act play, Madame Butterfly: A Tragedy of Japan, which, after premiering in New York in 1900, moved on to London, where Puccini saw it in the summer of that year.
