The Mikado, or The Town of Titipu, is a comic opera in two acts, with music by Arthur Sullivan and libretto by W. S. Gilbert, their ninth of fourteen operatic collaborations. It remains the most frequently performed Savoy Opera and it is especially popular with amateur and school productions. The work has been translated into numerous languages and is one of the most frequently played musical theatre pieces in history.

By setting the opera in Japan, an exotic locale far away from Britain, this allowed Gilbert to satirize British politics and institutions more freely by disguising them as Japanese. Gilbert used foreign or fictional locales in several operas, including The Mikado, Princess Ida, The Gondoliers, Utopia Limited, and The Grand Duke, to soften the impact of his pointed satire of British institutions.
