The Mikado, or The Town of Titipu is a two-act operetta. The book and lyrics were written by W. S. Gilbert. The music was written by Arthur Sullivan. The operetta premiered 14 March 1885 at the Savoy Theatre, London, with the D'Oyly Carte Opera Company. 

The Mikado is the ninth of the fourteen Gilbert and Sullivan operettas. It had 672 performances in its original run. This was the longest original run of any Gilbert and Sullivan operetta.

At the time of the operetta's creation, London was overwhelmed with all things Japanese: tea shops, kimonos, fans, etc. Gilbert reported that he got the idea for The Mikado when a Japanese sword fell from the wall of his study.
